Active Job: Add note about ability to configure adapters on per job basis in CHANGELOG and release notes

Remove last uses of `@env[]` and `@env[]=`

Active Job: Add note about ability to configure adapters on per job basis in CHANGELOG and release notes.

schema_load triggers 2nd schema_load (via locking)

Currently, loading the schema (schema_load)
accesses the locking column (locking_column)
which defaults the value (reset_locking_column)
which invalidates the schema (reload_schema_from_cache)
which forces another schema load.

Good news:
The second schema_load does accesses locking_column,
but locking_column is set, so it does not reset_locking_column
and it does not trigger an infinite loop.

The solution is not invalidate the cache while default locking_column
