The neutron-opflex-agent needs to be notified when the
subnets of a VRF have changed. This happens under the
following conditions:
1) When a subnetpool referencing a VRF is created, deleted, or
has its prefixes updated
2) Whenever subnets on networks whose BD is associated with
the unrouted VRF or any tenant's default VRF are created or deleted
3) When unscoped subnets change VRFs (happens as a result of
attaching and detaching interfaces on a router)

(cherry picked from commit 8cbb5f2cc2)
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.
