Cluster 26. Renaming pcs resource.

Below procedure found in:
https://bugzilla.redhat.com/show_bug.cgi?id=1126835 and tested by changing of the name of the resource type "ocf:heartbeat:VirtualDomain":

First:

1. make resource unmanaged: pcs resource unmanage resource-old-name
2. If this is VirtualDomain resource:
1. change old-name to the new-name in XML definition files of your VM.

Backup existing config:

pcs cluster cib /tmp/cib.xml

Globally (not only first occurrence) change old-name to the new-name: 

sed 's/resource-old-name/resource-new-name/g' -i /tmp/cib.xml

Verify changes:

vi /tmp/cib.xml 

Push changed config to the cluster:

pcs cluster cib-push /tmp/cib.xml

Verify name change:

pcs status

Verify name change in the config dump:

pcs config | grep resource-new-name

Make resource managed again:
pcs resource manage resource-new-name
