These tests are intended to catch issues in upgrading HGE. However:
* the tests are very convoluted and hard to understand,
* we can only run a small subset of Python tests that don't mutate any data or metadata, and
* I have never seen them fail for a legitimate reason, but I've seen a lot of flakes.
While we do believe it's important to test that upgrades don't break the stored introspection, these tests don't seem to be doing that any more. I humbly request that we delete them now and either (a) figure out how to test this properly, or (b) just wait for v3, which does away with reintrospecting on server startup entirely.

This rewrites the last couple of Python tests that were failing when run with a separate HGE binary per test class. The changes are as follows:
1. The event triggers tests, naming conventions tests, and subscriptions tests all generate a new source DB per test, so can run in parallel.
2. The scheduled triggers tests use the correct URL for the trigger service when the port is generated randomly.
3. Whitespace and trailing commas are added to the scheduled triggers tests.
4. Support for SQL Server is added to _hge.py_ so the naming conventions test that runs on SQL Server passes. (The other SQL Server tests do not pass and we're not going to bother with them for now.)
5. Container names are fixed in _run.sh_.
6. _run.sh_ and _run-new.sh_ don't pull images explicitly as it's annoying when running tests a lot. If you want to pull the latest versions, just run `docker compose pull` from the _server/tests-py_ directory, or the root directory. (If you don't have the images at all, they'll still be pulled automatically.)

We no longer support this and therefore don't run tests against it.
This also refactors the code a little so it doesn't have to skip running a PostgreSQL-specific test against MS SQL Server.

This has two purposes:
* When running the Python integration tests against a running HGE instance, with `--hge-url`, it will check the environment variables available and actively skip the test if they aren't set. This replaces the previous ad-hoc skip behavior.
* More interestingly, when running against a binary with `--hge-bin`, the environment variables are passed through, which means different tests can run with different environment variables.
On top of this, the various services we use for testing now also provide their own environment variables, rather than expecting a test script to do it.
In order to make this work, I also had to invert the dependency between various services and `hge_ctx`. I extracted a `pg_version` fixture to provide the PostgreSQL version, and now pass the `hge_url` and `hge_key` explicitly to `ActionsWebhookServer`.

We plan on creating the source database dynamically, in the test setup.
This means that (a) we cannot assume that the metadata database and the
source database are the same, and (b) we need to drop and re-add the
source in code, not in YAML.
This changeset prepares the code for the introduction of a separate
source database, but doesn't go there yet. The separation is already
done but is too big to review in one go, so I have split this out.

Let's put it in one place.
This is a precursor to moving database provisioning into the Python
integration tests.

Rather than hard-coding hostnames and ports, we can (and already do) inject these into the HGE process using environment variables.

It feels a lot more sensible as we never run on more than one backend at a time.
This also removes the `check_file_exists` parameter from the setup functions; it never worked. It was always set to the result of a comparison between a backend name and a function, which was always `False`. Enabling it breaks things.

We have a lot of `assert st_code == 200` scattered about. This is a
problem because (a) it makes the code harder to parse and (b) the error
message is lacking; I have seen a few flaky tests which were impossible
to diagnose because I didn't know what the response _should_ be.
This reduces the number of places in which we perform this assertion
(moving most of them to `HGECtx.execute_query`), so that we can have a
better chance of seeing a useful error message on test failure.

This essentially restores the original code from c425b554b8
(https://github.com/hasura/graphql-engine/pull/4013). Prior to this
commit we would slurp messages as fast as possible from the database
(one thing c425b55 fixed).
Another thing broken as a consequence of the same logic was the
removeEventFromLockedEvents logic which unlocks in-flight events
(breaking at-least-once delivery)
Some archeology, post-c425b55:
- cc8e2ccc erroneously attempted to refactor using `bracket`, resulting
in the same slurp-all-events behavior (since we don't ever wait for
processEvent to complete)
- at some point event processing within a batch is made serial, this
reported as a bug. See: https://github.com/hasura/graphql-engine/issues/5189
- in 0ef52292b5 (which I approved...) an `async` is added, again
causing the same issue...

This claws back ~7min from integration tests (run serially, as with `dev.sh test --integration`
Further improvements would do well to focus on optimizing metadata operations, as `setup` dominates

Earlier, while creating the event trigger's internal postgres trigger, we used to get the name of the table from the `TG_TABLE_NAME` special trigger variable. Using this with normal tables works fine, but it breaks when the parent table is partitioned because we associate the ET configuration in the schema only with the original table (as it should be).
In this PR, we supply the table name and schema name through template variables instead of using `TG_TABLE_NAME` and `TG_TABLE_SCHEMA`, so that event triggers work with a partitioned table as well.
TODO:
- [x] Changelog
- [x] unit test (ET on partition table)

* Test working through a backlog of change events
* Use a slightly more performant threaded http server in eventing pytests
This helped locally but not on CI it seems...
* Rework event processing for backpressure. Closes#3839
With loo low `HASURA_GRAPHQL_EVENTS_FETCH_INTERVAL` and/or slow webhooks
and/or too small `HASURA_GRAPHQL_EVENTS_HTTP_POOL_SIZE` we might
previously check out events from the DB faster than we can service them,
leading to space leaks, weirdness, etc.
Other changes:
- avoid fetch interval sleep latency when we previously did a non-empty
fetch
- prefetch event batch while http pool is working
- warn when it appears we can't keep up with events being generated
- make some effort to process events in creation order so we don't
starve older ones.
ALSO NOTE: HASURA_GRAPHQL_EVENTS_FETCH_INTERVAL changes semantics
slightly, since it only comes into play after an empty fetch. The old
semantics weren't documented in detail, so I think this is fine.
* run basic tests after upgrade
* terminate before specifying file in pytest cmd
* Move fixture definitions out of test classes
Previously we had abstract classes with the fixtures defined
in them. The test classes then inherits these super classes. This
is creating inheritence problems, especially when you want to just
inherit the tests in class, but not the fixtures. We have now moved
all those fixture definitions outside of the class (in conftest.py).
These fixtures are now used by the test classes when and where they
are required.
* Run pytests on server upgrade
Server upgrade tests are run by
1) Run pytest with schema/metadata setup but do not do schema/metadata
teardown
2) Upgrade the server
3) Run pytest using the above schema and teardown at the end of the
tests
4) Cleanup hasura metadata and start again with next set of tests
We have added options --skip-schema-setup and --skip-schema-teardown to
help running server upgrade tests.
While running the tests, we noticed that error codes and messages for
some of the tests have changed. So we have added another option to
pytest `--avoid-error-message-checks`. If this flag is set, and if
comparing expected and response message fails, and if the expected
response has an error message, Pytest will throw warnings instead of an
error.
* Use marks to specify server-upgrade tests
Not all tests can be run as serve upgrade tests, particularly those
which themselves change the schema. We introduce two pytest markers.
Marker allow_server_upgrade_test will add the test into the list of
server upgrade tests that can be run. skip_server_upgrade_test
removes it from the list.
With this we have added tests for queries, mutations, and selected
event trigger and remote schema tests to the list of server upgrade
tests.
* Remove components not needed anymore
* Install curl
* Fix error in query validation
* Fix error in test_v1_queries.py
* install procps for server upgrade tests
* Use postgres image which has postgis installed
* set pager off with psql
* quote the bash variable WORKTREE_DIR

We add a new pytest flag `--accept` that will automatically write back
yaml files with updated responses. This makes it much easier and less
error-prone to update test cases when we expect output to change, or
when authoring new tests.
Second we make sure to test that we actually preserve the order of the
selection set when returning results. This is a "SHOULD" part of the
spec but seems pretty important and something that users will rely on.
To support both of the above we use ruamel.yaml which preserves a
certain amount of formatting and comments (so that --accept can work in
a failry ergonomic way), as well as ordering (so that when we write yaml
the order of keys has meaning that's preserved during parsing).
Use ruamel.yaml everywhere for consistency (since both libraries have
different quirks).
Quirks of ruamel.yaml:
- trailing whitespace in multiline strings in yaml files isn't written
back out as we'd like: https://bitbucket.org/ruamel/yaml/issues/47/multiline-strings-being-changed-if-they
- formatting is only sort of preserved; ruamel e.g. normalizes
indentation. Normally the diff is pretty clean though, and you can
always just check in portions of your test file after --accept
fixup
Update trigger is failing if any json/geometry columns are present in
event payload rows. Use '*<>' operator instead of '<>' to compare the
internal binary representation of rows if '<>' doesn’t work.
Examples
1) `
pytest --hge-urls "http://127.0.0.1:8080" --pg-urls "postgresql://admin@127.0.0.1:5432/hge_tests" -vv
`
2) `pytest --hge-urls "http://127.0.0.1:8080" "http://127.0.0.1:8081" --pg-urls "postgresql://admin@127.0.0.1:5432/hge_tests" "postgresql://admin@127.0.0.1:5432/hge_tests2" -vv

### Solution and Design
<!-- How is this issue solved/fixed? What is the design? -->
<!-- It's better if we elaborate -->
#### Reducing execution time of tests
- The Schema setup and teardown, which were earlier done per test method, usually takes around 1 sec.
- For mutations, the model has now been changed to only do schema setup and teardown once per test class.
- A data setup and teardown will be done once per test instead (usually takes ~10ms).
- For the test class to get this behaviour, one can can extend the class `DefaultTestMutations`.
- The function `dir()` should be define which returns the location of the configuration folder.
- Inside the configuration folder, there should be
- Files `<conf_dir>/schema_setup.yaml` and `<conf_dir>/schema_teardown.yaml`, which has the metadata query executed during schema setup and teardown respectively
- Files named `<conf_dir>/values_setup.yaml` and `<conf_dir>/values_teardown.yaml`. These files are executed to setup and remove data from the tables respectively.
#### Running Graphql queries on both http and websockets
- Each GraphQL query/mutation is run on the both HTTP and websocket protocols
- Pytests test parameterisation is used to achieve this
- The errors over websockets are slightly different from that on HTTP
- The code takes care of converting the errors in HTTP to errors in websockets
#### Parallel executation of tests.
- The plugin pytest-xdist helps in running tests on parallel workers.
- We are using this plugin to group tests by file and run on different workers.
- Parallel test worker processes operate on separate postgres databases(and separate graphql-engines connected to these databases). Thus tests on one worker will not affect the tests on the other worker.
- With two workers, this decreases execution times by half, as the tests on event triggers usually takes a long time, but does not consume much CPU.
