Symptom: charm stuck in blocked state because of the service designate-agent failing

App Version Status Scale Charm Channel Rev Exposed Message
designate caracal blocked 1 designate latest/edge 224 no Services not running that should be: designate-agent

The charm requires designate-agent service to be running, yet this one was removed in Caracal
See the description:
https://docs.openstack.org/releasenotes/designate/2024.1.html
>Designate-agent removal is complete in this version of designate.

The service to be checked is defined as list in the code. Yet it should be handled for backward compatibility it should be removed from the list if the version is >= Caracal(2024.1)

See the code excerpt here:
https://opendev.org/openstack/charm-designate/src/branch/master/src/lib/charm/openstack/designate.py#L314

I also see that the package still exist while it should be removed
