cluster/ec: Node uuid xattr support update for EC
Problem:
The change in EC to return list of node uuids for
GF_XATTR_NODE_UUID_KEY was causing problems with
geo-rep.
Fix:
This patch will allow to get the single node uuid
as it was doing before with the key
"GF_XATTR_NODE_UUID_KEY", and will also allow to get
the list of node uuids by using a new key
"GF_XATTR_LIST_NODE_UUIDS_KEY". This will solve
the problem with geo-rep and any other features which
were depending on this.
BUG: 1462790
