Pacemaker can drive systemd-managed services for quite some time.

Provided that the project/daemon you care about carries the unit
file, you can use that unless there are distinguished roles for the
provided service within the cluster (like primary+replicas), there's
a need to run multiple varying instances of the same service,
or other cluster-specific features are desired.

For dovecot, I can see:
# rpm -ql dovecot | grep \.service
/usr/lib/systemd/system/dovecot.service

If you miss something with the generic approach per above, and there's
no fitting open-sourced RA around then it's probably your last resort.

For instance, there was once an agent written in C (highly unusual),
but seems abandoned a long time ago:
