Eager locking a single node should only acquire a single lock
-------------------------------------------------------------

                 Key: ISPN-715
                 URL: https://jira.jboss.org/browse/ISPN-715
             Project: Infinispan
          Issue Type: Feature Request
            Reporter: Erik Salter
            Assignee: Manik Surtani


The new eager/explicit lock for a single node feature in 4.2.0 can be further optimized.  Right now, a local lock and a lock on the node where the key is hashed is acquired.  To increase throughput and minimize deadlock occurrences, we should only acquire the one lock (on the node).  

(Obviously, if the key is hashed to the local node, the local lock and the node lock are one in the same).
