Public bug reported:
With ML2/OVN if one create about 1000 of static routes on a router, the
addition takes <10seconds but deletion of those static routes takes
about ~8 minutes.
That is because neutron sends a separate deletion command to OVN for
each of the static route, which is very inefficient, instead of doing it
in a single transaction.
Neutron version: latest/main branch
Deployment tool: devstack
