defaults: avoid getting stuck (ceph --connect-timeout)

Sometime the playbook gets stuck because even with `--connect-timeout=`
option, the connexion to the existing ceph cluster never timeout.

As a workaround, using `timeout` command provided by coreutils will
actually timeout if we can't connect to the cluster.
