When moving a host to maintenance in a hyper-converged cluster, check that quorum is available. If quorum is not met, and host is moved to maintenance - the gluster volume will become read-only and VMs paused.
Also, if rebalance, remov-brick or self-heal is running, host should not be moved to maintenance
Version-Release number of selected component (if applicable):
Users may need a way to override this warning and move host to maintenance.
