ceph-dashboard: copy TLS cert/key on monitor
ceph-dashboard: copy TLS cert/key on monitor

The ceph-dashboard role is executed on the mgr nodes so the TLS cert/key
files are copied to those nodes.
But we are running importing the cert/key files into the ceph
configuration on the monitor.

Closes: #5557
