Description of problem:
In case Octavia is upgraded from OSP13 to OSP16, the support for UDP listener becomes available and the webhook that enforces DNS resolution over TCP is removed from the cluster. In order to ensure the DNS resolution is working fine for any new pod that gets created the DNS service must be recreated so the UDP listeners becomes available on the new amphora.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Upgrade Octavia from OSP13 to OSP16 with amphora
2. Verify the Kuryr Controller keeps retrying to add pool on a load balancer with old amphora and as not allowed keeps restarting
Octavia component update should be part of OSP13 to OSP16 upgrade which is not supported at the moment, so QE verification only confirms that the fix code is present on 4.5.0-0.nightly-2020-05-29-005153
