[Bug 1949230] [NEW] OVN Octavia provider driver should implement allowed_cidrs to enforce security groups on LB ports

 

Public bug reported:

Octavia can use OVN as a provider driver using it's driver framework.
The OVN Octavia provider driver, part of ML2/OVN, does not implement all
of the functionality of the Octavia API [1].  One feature that should be
supported is allowed_cidrs.

The Octavia allowed_cidrs functionality allows Octavia to manage and
communicate the CIDR blocks allowed to address an Octavia load balancer.
Implementing this in the OVN provider driver would allow load balancers
to be only accessible from specific CIDR blocks, a requirement for
customer security ina number of scenarios.
