Robert Kukura 94dfa082ca [AIM] Don't override loading of SG rules when validating
Previously, the query for security groups during validation overrode
the loading of the rules from subquery to joined to minimize the
number of round-trips to the DB. Upstream neutron, in
https://review.opendev.org/#/c/660174/, changed the default loading
from subquery to dynamic. This has been back-ported through queens,
and breaks our override, so the override is replaced with a REVISIT.

README.rst

Group Based Policy (GBP) provides declarative abstractions for achieving scalable intent-based infrastructure automation.

GBP complements the OpenStack networking model with the notion of policies that can be applied between groups of network endpoints. As users look beyond basic connectivity, richer network services with diverse implementations and network properties are naturally expressed as policies. Examples include service chaining, QoS, path properties, access control, etc.

GBP allows application administrators to express their networking requirements using a Group and a Policy Rules-Set abstraction. The specifics of policy rendering are left to the underlying pluggable policy driver.

GBP model also supports a redirect operation that makes it easy to abstract and consume complex network service chains and graphs.

Checkout the GBP wiki page for more detailed information: <https://wiki.openstack.org/wiki/GroupBasedPolicy>

The latest code is available at: <http://git.openstack.org/cgit/openstack/group-based-policy>.

GBP project management (blueprints, bugs) is done via Launchpad: <https://launchpad.net/group-based-policy>
