We use a helper service to start a webhook-based authentication service for some tests. This moves the initialization of the service out of _test-server.sh_ and into the Python test harness, as a fixture.
In order to do this, I had to make a few changes. The main deviation is that we no longer run _all_ tests against an HGE with this authentication service, just a few (those in _test_webhook.py_). Because this reduced coverage, I have added some more tests there, which actually cover some areas not exacerbated elsewhere (mainly trying to use webhook credentials to talk to an admin-only endpoint).
The webhook service can run both with and without TLS, and decide whether it's necessary to skip one of these based on the arguments passed and how HGE is started, according to the following logic:
* If a TLS CA certificate is passed in, it will run with TLS, otherwise it will skip it.
* If HGE was started externally and a TLS certificate is provided, it will skip running without TLS, as it will assume that HGE was configured to talk to a webhook over HTTPS.
* Some tests should only be run with TLS; this is marked with a `tls_webhook_server` marker.
* Some tests should only be run _without_ TLS; this is marked with a `no_tls_webhook_server` marker.
The actual parameterization of the webhook service configuration is done through test subclasses, because normal pytest parameterization doesn't work with the `hge_fixture_env` hack that we use. Because `hge_fixture_env` is not a sanctioned way of conveying data between fixtures (and, unfortunately, there isn't a sanctioned way of doing this when the fixtures in question may not know about each other directly), parameterizing the `webhook_server` fixture doesn't actually parameterize `hge_server` properly. Subclassing forces this to work correctly.
The certificate generation is moved to a Python fixture, so that we don't have to revoke the CA certificate for _test_webhook_insecure.py_; we can just generate a bogus certificate instead. The CA certificate is still generated in the _test-server.sh_ script, as it needs to be installed into the OS certificate store.
Interestingly, the CA certificate installation wasn't actually working, because the certificates were written to the wrong location. This didn't cause any failures, as we weren't actually testing this behavior. This is now fixed with the other changes.

This introduces an `ErrorMessage` newtype which wraps `Text` in a manner which is designed to be easy to construct, and difficult to deconstruct.
It provides functionality similar to `Data.Text.Extended`, but designed _only_ for error messages. Error messages are constructed through `fromString`, concatenation, or the `toErrorValue` function, which is designed to be overridden for all meaningful domain types that might show up in an error message. Notably, there are not and should never be instances of `ToErrorValue` for `String`, `Text`, `Int`, etc. This is so that we correctly represent the value in a way that is specific to its type. For example, all `Name` values (from the _graphql-parser-hs_ library) are single-quoted now; no exceptions.
I have mostly had to add `instance ToErrorValue` for various backend types (and also add newtypes where necessary). Some of these are not strictly necessary for this changeset, as I had bigger aspirations when I started. These aspirations have been tempered by trying and failing twice.
As such, in this changeset, I have started by introducing this type to the `parseError` and `parseErrorWith` functions. In the future, I would like to extend this to the `QErr` record and the various `throwError` functions, but this is a much larger task and should probably be done in stages.
For now, `toErrorMessage` and `fromErrorMessage` are provided for conversion to and from `Text`, but the intent is to stop exporting these once all error messages are converted to the new type.

* 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
Changes compared to `/v1alpha1/graphql`
* Changed all graphql responses in **/v1/graphql** endpoint to be 200. All graphql clients expect responses to be HTTP 200. Non-200 responses are considered transport layer errors.
* Errors in http and websocket layer are now consistent and have similar structure.
