All of the additional lookup logic was essentially duplicating
a relationship property of 'load_on_pending=True', which tells
SQLAlchemy to lookup the relationship during object creation [1].
So we can dump all of this logic and just use that option.

This switches to the use of subqueries for 1-m relationships
which will result in a higher constant query factor but will
eliminate the potential for cross-product explosions.

This adds revises_on_change for the following models
and API tests to ensure the correct behavior:
* port security (network and port)
* DNS domain (network and port)
* extra dhcp opts (port)
* extra routes (router)
* subnet service type (subnet)
Additionally, it configures the DNS extension to be loaded
in the gate since the extension is enabled for tempest.
