Prevents users from submitting out-of-date metadata to metadata-mutating APIs.

* Stop shutdown handler retaining the whole serveCtx
This might look like quite a strange way to write the function but it's
the only way I could get GHC to not capture `serveCtx` in the shutdown
handler.
Fixes the metadata issue in #344
* Force argumentNames
The arguments list is often empty so we end up with a lot of duplicate
thunks if this value is not forced.
* Increase sharing in nullableType and nonNullableType
The previous definitions would lead to increased allocation as it would
destory any previously created sharing. The new definition only allocate
a fresh constructor if the value is changed.
* Add memoization for field parsers
It was observed in #344 that many parsers were not being memoised which
led to an increase in memory usage. This patch generalisation memoisation so
that it works for FieldParsers as well as normal Parsers.
There can still be substantial improvement made by also memoising
InputFieldParsers but that is left for future work.

- Expands `MonadMetadataStorage` with operations related to async actions and setting/updating metadata
GitOrigin-RevId: 53386b7b2d007e162050b826d0708897f0b4c8f6
* Add ekg-core to build-executable .cabal
* Move creation of EKG Store to Main.hs
This helps to share metrics between pro and OSS and
helps surface the metrics from OSS in Datadog via
Pro.

This fixes#3759. Also, while we’re at it, also improve the way
invalidations are synced across instances so enums and remote schemas
are appropriately reloaded by the schema syncing process.
* save permissions, relationships and collections in catalog with 'is_system_defined'
* Use common stanzas in the .cabal file
* Refactor migration code into lib instead of exe
* Add new server test suite that exercises migrations
* Make graphql-engine clean succeed even if the schema does not exist
* Separate DB and metadata migrations
* Refactor Migrate.hs to generate list of migrations at compile-time
* Replace ginger with shakespeare to improve performance
* Improve migration log messages
* allow customizing GraphQL root field names, close#981
* document v2 track_table API in reference
* support customising column field names in GraphQL schema
* [docs] add custom column fields doc in API reference
* add tests
* rename 'ColField' to 'ColumnField'
* embed column's graphql field in 'PGColumnInfo'
-> Value constructor of 'PGCol' is not exposed
-> Using 'parseJSON' to construct 'PGCol' in 'FromJSON' instances
* avoid using 'Maybe TableConfig'
* refactors & 'custom_column_fields' -> 'custom_column_names'
* cli-test: add configuration field in metadata export test
* update expected keys in `FromJSON` instance of `TableMeta`
* use `buildSchemaCacheFor` to update configuration in v2 track_table
* remove 'GraphQLName' type and use 'isValidName' exposed from parser lib
* point graphql-parser-hs library git repo to hasura
* support 'set_table_custom_fields' query API & added docs and tests
* use positional arguments in SQL functions
* only allow omitting set of last arguments in functions
* disallow omitting of a non default argument in functions
These changes also add a new type, PGColumnType, between PGColInfo and
PGScalarType, and they process PGRawColumnType values into PGColumnType
values during schema cache generation.
* Listens for SIGTERM as the termination signal
* Stops accepting new connections once the signal is received
* Waits for all connections to be drained, before shutting down
* Forcefully kills all pending connections after 30 seconds
Currently this does not send a close message to websocket clients, I'd
like to submit that change as a separate pull request, but at least this
solve my biggest concern which is not getting confirmation for mutations
while restarting the server.
