BZ #1172366 - fix some pcmk constraints

[cwolferh]

https://bugzilla.redhat.com/show_bug.cgi?id=1172366

Constraints with an incorrect name specified (i.e., no -clone) could
cause issues for pcs commands immediately following. Also remove
groups for cloned resources.

Before this patch, I observed in pacemaker.log messages such as:

Dec 11 15:33:28 [6855] c1a2.example.com stonith-ng:    error: unpack_order_template:    Invalid constraint 'order-neutron-ovs-cleanup-neutron-netns-cleanup-mandatory': No resource or template named 'neutron-ovs-cleanup'
Dec 11 15:33:28 [6855] c1a2.example.com stonith-ng:    error: unpack_order_template:    Invalid constraint 'order-neutron-netns-cleanup-neutron-agents-mandatory': No resource or template named 'neutron-netns-cleanup'

Now I do not.

Also, removed the unnecessary groups so no longer see output like:

Debug: /usr/sbin/pcs resource group add nosql mongod
Error: cannot group clone resources

The error in https://bugzilla.redhat.com/show_bug.cgi?id=1172366 also did not occur again in my test with this patch (theory was the prior bad constraints were causing an issue for ceilometer-related pcs commands, see comment 11).
