remove container_exec_cmd_mgr fact

Iterating over all monitors in order to delegate a `
{{ container_binary }}` fails when collocating mgrs with mons, because
ceph-facts reset `container_exec_cmd` to point to the first member of
the monitor group.

The idea is to force `container_exec_cmd` to be reset in ceph-mgr.
This commit also removes the `container_exec_cmd_mgr` fact.
