Description of problem:
Overcloud deployment fails If ceph dashboard is being deployed with using cephadm. The exact error is:
FATAL | Run pacemaker restart if the config file for the service changed | central-controller-0 | error={"changed": false, "error": "Failed running command", "msg": "Error running /var/lib/container-config-scripts/pacemaker_restart_bundle.sh haproxy haproxy-bundle haproxy-bundle Started. rc: 1, stdout: , stderr: Waiting for the cluster to apply configuration changes (timeout: 600 seconds)...\nresource 'haproxy-bundle' is not running on any node\nWaiting for the cluster to apply configuration changes (timeout: 600 seconds)...\nError: resource 'haproxy-bundle' is not running on any node\nError: Errors have occurred, therefore pcs is unable to continue\n"}

which happens because haproxy fails to bind socket for ceph dashboard proxy:
Starting proxy ceph_dashboard: cannot bind socket (Address already in use) [192.168.24.82:8444]

Because ceph-mgr is binded on that socket for all interfaces:
# netstat -putna | grep 8444
tcp6       0      0 :::8444                 :::* LISTEN      6444/ceph-mgr

ceph-mgr should not be listening on all interfaces (which is default unless specifically configured) but specific IP address should be set for each ceph-mgr host.

The specific IP addresses where ceph dashboard module should be listening are actually set for each host in ceph cluster:
# ceph config dump | grep server_addr
  mgr                                                                       advanced  mgr/dashboard/central-controller-0-pwaxfm/server_addr      172.23.1.11                                                                                                                          * 
  mgr                                                                       advanced  mgr/dashboard/central-controller-1-iczifz/server_addr      172.23.1.42                                                                                                                          * 
  mgr                                                                       advanced  mgr/dashboard/central-controller-2-qxfada/server_addr      172.23.1.25


The problem is that the name of the hosts do not match the name with which the ceph-mgr was started:
# ps ax| grep ceph-mgr
   6442 ?        Ss     0:00 /dev/init -- /usr/bin/ceph-mgr -n mgr.central-controller-0.pwaxfm -f --setuser ceph --setgroup ceph --default-log-to-file=false --default-log-to-stderr=true --default-log-stderr-prefix=debug

The difference is in last "-" versus ".":
central-controller-0-pwaxfm vs. central-controller-0.pwaxfm

It comes probably from these code:
https://opendev.org/openstack/tripleo-ansible/src/branch/master/tripleo_ansible/roles/tripleo_cephadm/tasks/dashboard/configure_dashboard_backends.yml#L17-L33
where the name of the ceph-mgr node is being taken from container name which has dash and not a dot but ceph-mgr process is started with name including a dot.
