handler: fix call to container_exec_cmd in handler_osds

When unsetting the noup flag, we must call container_exec_cmd from the
delegated node (first mon member)
Also, adding a `run_once: true` because this task needs to be run only 1
time.

Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1792320
