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. Change-Id: I0de2488e24f1ef53a935dbc90ec6de6142bb4264
