### Description
The spock handler requires the request type to have a `ToJSON` instance AND a `FromJSON` instance. That's because we parse it from the received bytestring into its proper type.... and call `toJSON` on it to log it. This PR simplifies this, by keeping the intermediate `Value` obtained during parsing, and using it for logging. This has two consequences:
1. it removes the `ToJSON` constraint, which will remove some code down the line (esp. in Metadata)
2. it means we log the actual JSON object query we received, not the result of parsing it, meaning the logged object will contain fields that would have been ignored when parsing the actual value; this is both an upside (more accurate log) and a downside (could be more verbose / more confusing)
### Further work
Should this PR also remove all obsolete ToJSON instances while at it?
How do we test this?

### 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.

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...

Removing `schemaSyncDisable` flag and interpreting `schemaPollInterval` of `0` as disabling schema sync.
This change brings the convention in line with how action and other intervals are used to disable processes.
There is an opportunity to abstract the notion of an optional interval similar to how actions uses `AsyncActionsFetchInterval`.
This can be used for the following fields of ServeOptions, with RawServeOptions having a milliseconds value where `0` is interpreted as disable.
OptionalInterval:
```
-- | Sleep time interval for activities
data OptionalInterval
= Skip -- ^ No polling
| Interval !Milliseconds -- ^ Interval time
deriving (Show, Eq)
```
ServeOptions:
```
data ServeOptions impl
= ServeOptions
{
...
, soEventsFetchInterval :: !OptionalInterval
, soAsyncActionsFetchInterval :: !OptionalInterval
, soSchemaPollInterval :: !OptionalInterval
...
}
```
Rather than encoding a `Maybe OptionalInterval` in RawServeOptions, instead a `Maybe Milliseconds` can be used to more directly express the input format, with the ServeOptions constructor interpreting `0` as `Skip`.
Current inconsistencies:
* `soEventsFetchInterval` has no value interpreted as disabling the fetches
* `soAsyncActionsFetchInterval` uses an `OptionalInterval` analog in `RawServeOptions` instead of `Milliseconds`
* `soSchemaPollInterval` currently uses `Milliseconds` directly in `ServeOptions`
