Improve performance on metadata computation (#12785)

In this PR:

## Improve recompute metadata cache performance. We are aiming for
~100ms

Deleting relationMetadata table and FKs pointing on it
Fetching indexMetadata and indexFieldMetadata in a separate query as
typeorm is suboptimizing

## Remove caching lock

As recomputing the metadata cache is lighter, we try to stop preventing
multiple concurrent computations. This also simplifies interfaces

## Introduce self recovery mecanisms to recompute cache automatically if
corrupted

Aka getFreshObjectMetadataMaps

## custom object resolver performance improvement:  1sec to 200ms

Double check queries and indexes used while creating a custom object
Remove the queries to db to use the cached objectMetadataMap

## reduce objectMetadataMaps to 500kb

We used to stored 3 fieldMetadataMaps (byId, byName, byJoinColumnName).
While this is great for devXP, this is not great for performances.
Using the same mecanisme as for objectMetadataMap: we only keep byIdMap
and introduce two otherMaps to idByName, idByJoinColumnName to make the
bridge

## Add dataloader on IndexMetadata (aka indexMetadataList in the API)

## Improve field resolver performances too

## Deprecate ClientConfig
