b167120f96 server: add explicit export lists in OSS server and enforce with warning
We'll see if this improves compile times at all, but I think it's worth
doing as at least the most minimal form of module documentation.

This was accomplished by first compiling everything with
-ddump-minimal-imports, and then a bunch of scripting (with help from
ormolu)

**EDIT** it doesn't seem to improve CI compile times but the noise floor is high as it looks like we're not caching library dependencies anymore

8e88e73a52 server/mssql: add cascade to mssql_run_sql
<!-- Thank you for ss in the Title above ^ -->

## Description
<!-- Please fill thier. -->
<!-- Describe the changes from a user's perspective -->
We don't have dependency reporting mechanism for `mssql_run_sql` API i.e when a database object (table, column etc.) is dropped through the API we should raise an exception if any dependencies (relationships, permissions etc.) with the database object exists in the metadata.

This PR addresses the above mentioned problem by
-> Integrating transaction to the API to rollback the SQL query execution if dependencies exists and exception is thrown
-> Accepting `cascade` optional field in the API payload to drop the dependencies, if any
-> Accepting `check_metadata_consistency` optional field to bypass (if value set to `false`) the dependency check

### Related Issues
<!-- Please make surt title -->
<!-- Add the issue number below (e.g. #234) -->
Close #1853

### Solution and Design
<!-- How is this iss -->
<!-- It's better if we elaborate -->
The design/solution follows the `run_sql` API implementation for Postgres backend.

### Steps to test and verify
<!-- If this is a fehis is a bug-fix, how do we verify the fix? -->
- Create author - article tables and track them
- Defined object and array relationships
- Try to drop the article table without cascade or cascade set to `false`
- The server should raise the relationship dependency exists exception

459a7adbfb Add Types/FromIr changes for MySQL to work with the DataLoader
While it looks like a lot of work in FromIr.hs, you can rather review the type changes in `Hasura.Backends.MySQL.Types.Internal` and the changes to FromIr are only to reflect that. Essentially we're simplifying the FromIr code to not think about SQL-based joins: instead, FromIr produces fields necessary for the dataloader Plan/Execute to do their job properly.

I've done my best to ensure that all the hunks in the diff in this PR are minimal for slightly easier perusing.

I think future PRs will be more intentionally well structured, rather than created retroactively.

**Preceding PR:** #2549

**Next PR**: #2367

The tests have been run like this on my machine. I don't know more beyond that.

```
docker run -i -e "PYTEST_ADDOPTS=--color=yes" -e "TERM=xterm-256color" --net=host -v`pwd`:`pwd` -w`pwd`/server/tests-py chrisdone/hasura-pytest:b0f26f615 pytest  --hge-urls="http://localhost:8080"  --pg-urls="postgres://chinook:chinook@localhost:5432/chinook"  --backend mysql -k MySQL

7553ca170b Add backend modules for MySQL
This is the next part in the series of MySQL PRs.

**Purpose**: Adds the modules related to the generic backend abstraction. This is the penultimate PR.

The final PR will be the more substantial change made to FromIr (and small tweaks to Execute) that will connect all the things together including Python tests.

**Preceding PR:** #2529

**Next PR**: #2608

After #2529 is merged, this can be repointed to `main`. For now it's aimed at #2529, because then the diff display is simpler.

c4536e801c Correctly translate permissions on functions to SQL, and simplify Bool Exp IR
Prior to this change, the SQL expression that resulted from translating permissions on functions would refer to the table of the function's return type, rather than the set of rows selected from the function being called.

Now the SQL that results from translating permissions correctly refer to the selected rows.

This PR also contains the suggested additions of https://github.com/hasura/graphql-engine-mono/pull/2563#discussion_r726116863, which simplifies the Boolean Expression IR, but in turn makes the Schema Dependency Discovery algorithm work a bit harder.

We are changing the definition of `data OpExpG`, but the format accepted by its JSON parser remains unchanged. While there does exist a generically derived `instance ToJSON OpExpG` this is only used in the (unpublished) `/v1/metadata/dump_internal_state` API.

This is the next part in the series of MySQL PRs.

**Purpose**: Adds the Plan module for the data loader.

The `undefined` stubs in this PR have code already written, so they won't introduce a maintenance problem. They're only omitted for digestibility of the PR.

71af68e9e5 server: drop HasVersion implicit parameter (closes #2236)
The only real use was for the dubious multitenant option
--consoleAssetsVersion, which actually overrode not just
the assets version. I.e., as far as I can tell, if you pass
--consoleAssetsVersion to multitenant, that version will
also make it into e.g. HTTP client user agent headers as
the proper graphql-engine version.

I'm dropping that option, since it seems unused in production
and I don't want to go to the effort of fixing it, but am happy
to look into that if folks feels strongly that it should be
kept.

(Reason for attacking this is that I was looking into http
client things around blacklisting, and the versioning thing
is a bit painful around http client headers.)

47183e8a2c Add Execute part for the MySQL data loader
The Plan part is missing, because it needs support from FromIr. That'll come in a follow up commit.

**Next PR**: #2529

This is the result of splitting up the mega PR into more digestible chunks. This is the smallest subset I've been able to collect. Missing parts are noted in comments.

The code isn't reachable from Main, so it won't affect the test suite. It just gets compiled for now.

For context, this splits up work from https://github.com/hasura/graphql-engine-mono/pull/2332

11a454c2d6 server, pro: actually reformat the code-base using ormolu
This commit applies ormolu to the whole Haskell code base by running `make format`.

For in-flight branches, simply merging changes from `main` will result in merge conflicts.
To avoid this, update your branch using the following instructions. Replace `<format-commit>`
by the hash of *this* commit.

$ git checkout my-feature-branch
$ git merge <format-commit>^    # and resolve conflicts normally
$ make format
$ git commit -a -m "reformat with ormolu"
$ git merge -s ours post-ormolu

bdacf1bd23 server: remove ApplicativeDo from default extensions
I spent half the day reducing a weird compile failure here https://github.com/hasura/graphql-engine-mono/pull/1593/files#r713102990 to this https://gitlab.haskell.org/ghc/ghc/-/issues/17768#note_378004. Seems ApplicativeDo makes a mess of non-applicative monadic do in some cases. Given our rather localized use of ApplicativeDo, seemed a good idea to remove it from the list of default extensions.

It appears that ApplicativeDo also buries some unused return value warnings, so this PR also silences those. We should check that none of those warnings were warranted though.

9ca0bc1e5c server: remove identity notion from table columns
>

### Description
>
While adding [insert mutation schema parser for MSSQL backend](https://github.com/hasura/graphql-engine-mono/pull/2141) I also included [identity](https://en.wikipedia.org/wiki/Identity_column) notion to table columns across all backends. In MSSQL we cannot insert any value (even `DEFAULT` expression) into Identity columns. This behavior of identity columns is not same in Postgres as we can insert values. This PR drops the notion of identity in the column info. The context of identity columns for MSSQL is carried in `ExtraTableMetadata` type.

07fd7324c3 server: enable StrictData by default (fix hasura/graphql-engine#3941)
## Description

Almost all our data structures use strictness annotations, following [our styleguide's principle](https://github.com/hasura/graphql-engine/blob/master/server/STYLE.md#dealing-with-laziness) of "by default, use strict data types and lazy functions". The very few cases where we actually need laziness were already explicitly labelled as lazy with the `~` prefix operator.

This PR simply globally enables `StrictData`, allowing us to express records without `!()` on every field, but makes no attempt at cleaning existing code.

fe035125f4 server: drop LazyTxT newtype
This is a follow-up to #1959.

Today, I spent a while in review figuring out that a harmless PR change didn't do anything,
because it was moving from a `runLazy...` to something without the `Lazy`. So let's get
that source of confusion removed.

This should be a bit easier to review commit by commit, since some of the functions had
confusing names. (E.g. there was a misnamed `Migrate.Internal.runTx` before.)

The change should be a no-op.

fe8eabff19 server: fix the nullability of object relationships (fix hasura/graphql-engine#7201)
When adding object relationships, we set the nullability of the generated GraphQL field based on whether the database backend enforces that the referenced data always exists. For manual relationships (corresponding to `manual_configuration`), the database backend is unaware of any relationship between data, and hence such fields are always set to be nullable.

For relationships generated from foreign key constraints (corresponding to `foreign_key_constraint_on`), we distinguish between two cases:

1. The "forward" object relationship from a referencing table (i.e. which has the foreign key constraint) to a referenced table. This should be set to be non-nullable when all referencing columns are non-nullable. But in fact, it used to set it to be non-nullable if *any* referencing column is non-nullable, which is only correct in Postgres when `MATCH FULL` is set (a flag we don't consider). This fixes that by changing a boolean conjunction to a disjunction.
2. The "reverse" object relationship from a referenced table to a referencing table which has the foreign key constraint. This should always be set to be nullable. But in fact, it used to always be set to non-nullable, as was reported in hasura/graphql-engine#7201. This fixes that.

Moreover, we have moved the computation of the nullability from `Hasura.RQL.DDL.Relationship` to `Hasura.GraphQL.Schema.Select`: this nullability used to be passed through the `riIsNullable` field of `RelInfo`, but for array relationships this information is not actually used, and moreover the remaining fields of `RelInfo` are already enough to deduce the nullability.

This also adds regression tests for both (1) and (2) above.

fa152d842d server/postgres: optimize SQL query generation with LIMITs

### Description
>
This PR supersedes https://github.com/hasura/graphql-engine-mono/pull/1484. Apply `limit` to the table selection before joining relationship rows to improve query performance.

### Changelog

Fix https://github.com/hasura/graphql-engine/issues/5745

### Solution and Design
>
Prior to this change, we apply `LIMIT` and `OFFSET` to the outer selection from sub-query which includes joins for relationships. Now, we move `LIMIT` and `OFFSET` (if present) to inner selection of base table. But, this isn't done always! If there are order by relationships' columns we apply at the outer selection. To know more, please refer to [source code note](https://github.com/hasura/graphql-engine-mono/pull/2078/files#diff-46d868ee45d3eaac667cebb34731f573c77d5c9c8097bb9ccf1115fc07f65bfdR652).

c1bdc99334 Fix comment formatting to allow parsing in haddock-mode
This is just a one-off fix, based on running ormolu across
the code base, which uses GHC's parser in haddock mode.

### Description

Fixes several instances of illegal haddock comments.

### Related Issues

#1679

### Steps to test and verify

Run ormolu over the codebase. Prior to this change, it complains that it
can't parse certain files due to malformed Haddock comments, after it
doesn't (there are still some other errors).

### Limitations, known bugs & workarounds

This doesn't ensure that we don't introduce similar issues in the future;
that'll be dealt with once we implement #1679.
