Include subtransactions created by ActiveRecord::Base in counters
What does this MR do?
Changes in this merge request include subtransactions created directly by ActiveRecord::Base in our Prometheus counters. This moves this instrumentation from ApplicationRecord to existing ActiveRecord::Base patches.
It makes it possible to surface subtransactions created in migrations and other code from lib/gitlab/database.
