Force stop a single node pacemaker on yum update

Browse Source 
Currently package updates won't occur on a single node
non-HA pacemaker managed Controller because stopping
the node loses the quorum of 1.

This change gets the count of current nodes in the cluster and
if the count is 1 then specify --force when doing a pcs cluster stop.
