refactor: Update internal/db and oplog to use go-dbw package for database operations. (#1785)

* chore: Add new dbw dependency

* refactor: Convert to use dbw.DB

* refactor (db): Change GetTicket(...) signature

* feature (db tests): Added TestDeleteWhere(...)
Adding this allows us to eliminate a leak of the gorm library

* refactor: Add ctx to ScanRows(...) signature
This is required to refactor all the deprecated errors pkg calls.
This refactor required adding a context to quite a few call chains
and in particular the job scheduler bits

* feature (db/tests): Add support for test opt: WithTestLogLevel(...)
This test only option allows callers to specify a log level for the
underlying db package (where supported/applicable) when calling
TestSetup(...)

* refactor (db): Simplify Db type
Only store the underlying *DB and create the *RW on demand when
needed.

* refactor (oplog): Port to using dbw pkg for db operations

* refactor (db): Remove gormDB(...) func

* tests (db): Add unit tests for TestDeleteWhere(...)

* chore: make fmt changes to formatting
