7e79f8dc64 Fix migrations
Provides queries for fetching and inserting metadata into that database that do not assume there is a `resource_version` column. This means that will work when migrating to/from older versions.

59c01786fe Optimistic Metadata Locking
Add optimistic concurrency control to the ‘replace_metadata’ call.

Prevents users from submitting out-of-date metadata to metadata-mutating APIs.

See https://github.com/hasura/graphql-engine-mono/issues/472 for details.

* webhook calls are now supported

* relationships in sync actions

* initialise.sql is now in sync with the migration file

* fix metadata tests

* allow specifying arguments of actions

* fix blacklist check on check_build_worthiness job

* fix create_action_permission sql query

* drop permissions when dropping an action

* add a hdb_role view (and relationships) to fetch all roles in the system

* rename 'webhook' key in action definition to 'handler'

* allow templating actions wehook URLs with env vars

* use only REST semantics to resolve the webhook response

* use 'pk_columns' instead of 'columns' for update_by_pk input

* add python basic tests for single row mutations

* add action context (name) in webhook payload

* Async action response is accessible for non admin roles only if
  the request session vars equals to action's

* clean nulls, empty arrays for actions, custom types in export metadata

* async action mutation returns only the UUID of the action

* Basic sync actions python tests

* fix output in async query & add async tests

* add admin secret header in async actions python test

* document async action architecture in Resolve/Action.hs file

e47a8c4b86 incremental metadata: Clean up a few lingering loose ends
- Move MonadBase/MonadBaseControl instances for TxE into pg-client-hs
- Set the -qn2 RTS option by default to limit the parallel GC to 2
  threads
- Remove eventlog instrumentation
- Don’t rebuild the schema cache again after running a query that needs
  it to be rebuilt, since we do that explicitly now.
- Remove some redundant checks, and relocate a couple others.

780857fb19 Switch to a CPS implementation of Rule
This is significantly more performance, even without specialization,
which dramatically improves compile times.

447bac74e7 Split up Hasura.RQL.DDL.Schema.Cache
This should hopefully improve compile times by avoiding the need to
specialize everything at once.
