## Description ✍️
This PR introduces a new feature to enable/disable event triggers during logical replication of table data for PostgreSQL and MS-SQL data sources. We introduce a new field `trigger_on_replication` in the `*_create_event_trigger` metadata API. By default the event triggers will not fire for logical data replication.
## Changelog ✍️

### Short Changelog
Add option to enable/disable event triggers on logically replicated tables
### Related Issues ✍

### Solution and Design
- By default, triggers do **not** fire when the session mode is `replica` in Postgres, so if the `triggerOnReplication` is set to `true` for an event trigger we run the query `ALTER TABLE #{tableTxt} ENABLE ALWAYS TRIGGER #{triggerNameTxt};` so that the trigger fires always irrespective of the `session_replication_role`
- By default, triggers do fire in case of replication in MS-SQL, so if the `triggerOnReplication` is set to `false` for an event trigger we add a clause `NOT FOR REPLICATION` to the the SQL when the trigger is created/altered, which sets the `is_not_for_replication` for the trigger as `true` and it does not fire during logical replication.
### Steps to test and verify ✍
- Run hspec integration tests for HGE

When setting up a resource (typically some kind of web server) for use in tests, we need to remember to tear it down afterwards.
This moves this logic into one place, under the `TestResource` module.
Like `SetupAction`, it encapsulates setup and teardown, and also separates out waiting for the resource to be ready, so we don't accidentally leave it lying around in the case of a healthcheck failure.
Unlike `SetupAction`, it is monadic, and can be composed with other resources. In the future, we may want to adopt this logic for `SetupAction` too rather than using lists.

## Description
->
This PR allows DC agents to define custom aggregate functions for their scalar types.
### Related Issues
->
GDC-189
### Solution and Design
>
We added a new property `aggregate_functions` to the scalar types capabilities. This allows the agent author to specify a set of aggregate functions supported by each scalar type, along with the function's result type.
During GraphQL schema generation, the custom aggregate functions are available via a new method `getCustomAggregateOperators` on the `Backend` type class.
Custom functions are merged with the builtin aggregate functions when building GraphQL schemas for table aggregate fields and for `order_by` operators on array relations.
### Steps to test and verify
>
• Codec tests for aggregate function capabilities have been added to the unit tests.
• Some custom aggregate operators have been added to the reference agent and are used in a new test in `api-tests`.

## Description
This PR fixes hasura/graphql-engine#8345: when creating the final representation of a remote relationship to a remote schema (a `RemoteJoin`), we would mistakenly label ALL join fields in the selection set as being relevant to that one relationship: if there are more than one remote relationship to process in that selection set, that would be the union of all their join fields. The problem with this error is that, when processing remote relationships, we correctly ignore all the ones for which at least one join key is null. Consequently, this error would result in us ignoring remote relationships for which an _unrelated_ join key was null, resulting in that data missing in the final JSON result.
This PR simply ensures that the aggregation of fields that are passed to `createRemoteJoin` is pruned to only contain the fields relevant to the join being created. This is a very small change, and the bulk of this PR is the regression tests.

fix remote relationship to remote schema sometimes being erroneously null when multiple relationships are defined on the same table / graphql object ([#8345](https://github.com/hasura/graphql-engine/issues/8345))
