mgr/cephadm: Fix haproxy not being recognized as a proper daemon

Turns out daemon types != service types:

    cephadm [WRN] Found unknown service type haproxy on host smithi019
    cephadm [WRN] Found unknown service type keepalived on host smithi019

leading to `self.mgr.cache.get_daemons_by_service(spec.service_name())`
not returning any daemons.

Fixes: https://tracker.ceph.com/issues/51311
