common-ha : Fixing add node operation
Resource create for the added node referenced a variable new_node that was never passed. This led to a wrong schema type in the cib file and hence the added node always ended up in failed state. And also, resources were wrongly created twice and led to more errors. I have fixed the variable name and deleted the repetitive invocation of the recreate-resource function. The new node has to be added to the existing ganesha-ha config file for correct behaviour during subsequent add-node operations. This edited file has to be copied to all the other cluster nodes. I have added a fix for this as well.
