Description of problem:

In a standard ML2/OVS deployment there are 3 dhcp agents per network, each using a port. When converting to OVN a new port is created for OVN internal dhcp. After OVS->OVN migration there are 4 dhcp ports allocated. For most situations only the internal OVN dhcp port (labeled "distributed") is needed after.

In the migration ansible, I see cleanup code for dhcp- agent namespaces and services. Should these clean-up tasks remove the dhcp agent ports? or is additional instructions needed to fully cleanup/purge dhcp agents after migration.

Version-Release number of selected component (if applicable):
17.1
