ff62d5e0bf Migrate to GHC 8.10, upgrade dependencies. Closes #4517
This also seems to squash a stubborn space leak we see with
subscriptions (linking to canonical #3388 for reference).

This may also fix some of the "Unexpected exception" websockets
exceptions we are now surfacing (see e.g. #4344)

Also: dev.sh: fix hpc reporting

Initial work on this done by Vamshi.

Improve performance of replace_metadata on tracking tables. Closes #3802 (#4182)
* Improve performance of replace_metadata on tracking tables. Closes #3802

On the 1000 table track case this went from >20min to 8 seconds, the
bottleneck being all the former calls (for each table) to
buildSchemaCache.

* refactor replace metadata

Only save metadata in hdb_catalog schema and build schema cache (strictly)

* remove `withBuildSchemaCache` function

  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.

d86a3d9501 Use fine(er)-grained dependency tracking when building permissions
This changes TableCoreCacheT to internally record dependencies at a
per-table level. In practice, this dramatically improves the performance
of building permissions: it makes it far, far less likely for
permissions to be needlessly rebuilt because some unrelated table
changed.

* property tests for 'ReplaceMetadata' using QuickCheck

consumes more memory. Thus, CI is giving up while running property
tests.

4facb3c780 remove support for query templates (#2560)
query templates is a little known feature that lets you template rql
queries and serve them as rest apis. This is not relevant anymore
given the GraphQL interface and getting rid of it reduces the dev
time when adding features in few subsystems.

This feature has never been used outside hasura's internal projects or
documented or exposed through console and hence can safely be removed.

605f8633f3 fail on tracking table/function with name conflict (close #2020) (#2383)
Currently, we allow tracking of a table with the same name as an already tracked function, and vice-versa. This causes an issue when querying from GraphQL since it will only query the table and not the function. I've made changes to disallow this by throwing an error.

204cd3514b optimise server startup time (close #1430) (#2120)
1. Reuses postgres connections during startup which reduces the overhead of opening and closing connections. 
2. Faster schema cache building. This is done by fetching all the required data in a single sql statement.

c4c36e0ef4 schema cache sync improvements (#2098)
* build schema cache function without db setup

The setup shouldn't happen for sync. The database is already setup by the instance which generated the event. This means that the sync is now faster.

* use SQL loop to drop hdb_views schema views and routines with ordering

This avoids deadlocks when schema is being changed concurrently

* schema sync now only processes the latest event

This becomes useful when a lot of schema change
events happen while we are still processing an
earlier event.

5bafdce9a3 fix delete mutation returning incorrect data (fix #1794) (fix #1763) (#1827)
From `alpha-40` we've been using a `WHERE` clause to fetch required rows and generate mutation response. This has a few limitations like the requirement of a primary key/unique constraint. This also returns inconsistent data on `delete` mutation as mentioned in #1794. 
Now, we're using `VALUES (..)` (refer [here](https://www.postgresql.org/docs/current/sql-values.html)) expression to form virtual table rows in `SQL` to generate mutation response.

Internal changes:-
- Not to use primary key/unique constraint columns:-
  - Revert back to `ConstraintName` from `TableConstraint` in `TableInfo` type
  - Remove `tcCols` field in `TableConstraint` type
  - Modify `table_info.sql` and `fetchTableMeta` function `SQL`
- A test case to perform `delete` mutation and returning relational objects.

5f274b5527 fix mutation returning when relationships are present (fix #1576) (#1703)
If returning field contains nested selections then mutation is performed in two steps
1. Mutation is performed with returning columns of any primary key and unique constraints
2. returning fields are queried on rows returned by selecting from table by filtering with column values returned in Step 1.

Since mutation takes two courses based on selecting relations in returning field, it is hard to maintain sequence of prepared arguments (PrepArg) generated while resolving returning field. So, we're using txtConverter instead of prepare to resolve mutation fields.

fix sql generation for boolean expressions, closes #853 (#1037)
When using self referential relationships in boolean expressions, the exists clause incorrectly uses the table names to qualify columns which will be the same for parent table and the child table. This is now fixed by generating unique aliases as we traverse down the relationships.
