rhel7: "pcs resource move" should not lead to hard failover failures

Solution Unverified - Updated -

Issue

For example, let's say the resource res1 is on nodex, the administrator once execute the "pcs resource move res1", hence a cli-ban-res1/nodex is set in configuration, and then for whatever reason, he forgets to execute the "pcs resource clear res1" to remove the cli-ban line.

If, later, there is hard failover case which leads pacemaker to re-start all resources on nodex, but as the cli-ban-res1/nodex is always here for res1, the failover fails. We can't have this risk of failover failing just because an administrator has not executed a "pcs resource clear".
