[Jakub Libosvar <1928450@xxxxxxxxxxxxxxxxxx>]

Public bug reported:

Description of problem:
hosts_for_migration/[ovn-dbs] host group is populated wrongly and doesn't consider neutron_dhcp containers running elsewhere than neutron_server. 

Version-Release number of selected component (if applicable):
python3-networking-ovn-migration-tool-7.3.1-1.20200902233413.el8ost.noarch (RHOS 16.1.3)

How reproducible:
always

Steps to Reproduce:
1. Install overcloud with split control plane having neutron_dhcp and neutron_api running on distinct nodes
2.
3.

Actual results:
