A pull request for cleaning up small issues, bugs, redundancies and missing things in the BigQuery backend.
Summary:
1. Remove duplicate projection fields - BigQuery rejects these.
2. Add order_by to the test suite cases, as it was returning inconsistent results.
3. Add lots of in FromIr about how the dataloader approach is given support.
4. Produce the correct output structure for aggregates:
a. Should be a singleton object for a top-level aggregate query.
b. Should have appropriate aggregate{} and nodes{} labels.
c. **Support for nodes** (via array_agg).
5. Smooth over support of array aggregates by removing the fields used for joining with an explicit projection of each wanted field.

### Description
RunSQL commands are analyzed to detect whether they require a schema cache rebuild; in the case of Citus we were always returning `False`. This PR fixes this, and also removes the catch-all case, to make it explicit / obvious whenever we change this.

Remote relationships are now supported on SQL Server and BigQuery. The major change though is the re-architecture of remote join execution logic. Prior to this PR, each backend is responsible for processing the remote relationships that are part of their AST.
This is not ideal as there is nothing specific about a remote join's execution that ties it to a backend. The only backend specific part is whether or not the specification of the remote relationship is valid (i.e, we'll need to validate whether the scalars are compatible).
The approach now changes to this:
1. Before delegating the AST to the backend, we traverse the AST, collect all the remote joins while modifying the AST to add necessary join fields where needed.
1. Once the remote joins are collected from the AST, the database call is made to fetch the response. The necessary data for the remote join(s) is collected from the database's response and one or more remote schema calls are constructed as necessary.
1. The remote schema calls are then executed and the data from the database and from the remote schemas is joined to produce the final response.
### Known issues
1. Ideally the traversal of the IR to collect remote joins should return an AST which does not include remote join fields. This operation can be type safe but isn't taken up as part of the PR.
1. There is a lot of code duplication between `Transport/HTTP.hs` and `Transport/Websocket.hs` which needs to be fixed ASAP. This too hasn't been taken up by this PR.
1. The type which represents the execution plan is only modified to handle our current remote joins and as such it will have to be changed to accommodate general remote joins.
1. Use of lenses would have reduced the boilerplate code to collect remote joins from the base AST.
1. The current remote join logic assumes that the join columns of a remote relationship appear with their names in the database response. This however is incorrect as they could be aliased. This can be taken up by anyone, I've left a comment in the code.
### Notes to the reviewers
I think it is best reviewed commit by commit.
1. The first one is very straight forward.
1. The second one refactors the remote join execution logic but other than moving things around, it doesn't change the user facing functionality. This moves Postgres specific parts to `Backends/Postgres` module from `Execute`. Some IR related code to `Hasura.RQL.IR` module. Simplifies various type class function signatures as a backend doesn't have to handle remote joins anymore
1. The third one fixes partial case matches that for some weird reason weren't shown as warnings before this refactor
1. The fourth one generalizes the validation logic of remote relationships and implements `scalarTypeGraphQLName` function on SQL Server and BigQuery which is used by the validation logic. This enables remote relationships on BigQuery and SQL Server.

This reverts the remote schema type customisation and namespacing feature temporarily as we test for certain conditions.

> Known Issues
> It is not because of this PR, but evident after implementing this changes.
> Table comments section is not only showing table comments but also anything that has `SYS.EXTENDED_PROPERTIES` with the table id, we may need to fix this by adding more conditions while fetching the table comments
> issue: https://github.com/hasura/graphql-engine-mono/issues/1486
Update
> Found a common issue while testing this PR, and it happens for PG tables too, so keeping it as a different issue

Closes: https://github.com/hasura/graphql-engine/issues/6858
Description:
Following two things are done:
1. Show compatible functions in the Untracked custom functions list (i.e. even those with ROWTYPE arg)
2. When a function with ROWTYPE argument is tracked, a confirmatory dialogue box is shown. The text reads `This function can be added as a root field or a computed field inside a table` and the buttons reflect the options: `Add as root field`, `Add as computed field` (this will take the user to the Modify -> Add a computed field section of the first-row type argument)

### Description
The `statementTimeout` on RawSQL is not reset after changing a datasource. This causes an error when running SQL and parsing the results for DBs that don't support statement timeout property on the console.
### Affected components
- [x] Console
### Steps to test and verify
- Open /data/manage
- Click on any SQL Server DB.
- Go to Raw SQL
- Run any query
- Verify correct result

This is a minor refactor (part of `Internal/Parser.hs` is moved into `Internal/Input.hs`) to remove `Collect.hs-boot` and `Directives.hs-boot` files. Without these changes:
1. Most changes would trigger recompilation from the modules with hs-boot files.
1. haskell-language-server fails for some reason in the presence of hs-boot files.

adds foreign key functionality to mssql tables under Modify Tab.
Steps to test:
1. Connect an MSSQL data source.
2. Create a table
3. go to modify page
4. make sure the `Add foreign key `button is visible
5. click on `Add foreign key`, and try to add FK
6. after adding the FK, we will see the `edit` and `remove` button, try to edit and remove the FK

This implements the `snakeCaseTableName` method. It's part of the larger BigQuery PR at https://github.com/hasura/graphql-engine-mono/pull/1317, but @0x777 requested a smaller PR with this change.
