Description of problem:

After the deletion of network 377f875a-0f59-49d8-914f-7da5d1d34847 the DHCP agent is still present on controller:
~~~
ctl01 # podman ps
3a821689a8c8  htc-ospd01.ctlplane.x:8787/rhosp-rhel8/openstack-neutron-dhcp-agent:16.1.8          /bin/bash -c HAPR...  4 months ago    Up 7 weeks ago                  neutron-haproxy-qdhcp-377f875a-0f59-49d8-914f-7da5d1d34847
