Use an L1 Cache for SFSB context stored in a DIST mode Infinispan
-----------------------------------------------------------------

                 Key: EJBTHREE-2052
                 URL: https://jira.jboss.org/jira/browse/EJBTHREE-2052
             Project: EJB 3.0
          Issue Type: Sub-task
          Components: cache, Clustering
            Reporter: Brian Stansberry

With Infinispan DIST, an SFSB context may not be stored in Infinispan on the local node. (Even if it's originally stored locally, it may move due to a rehash following a topology change).

Keep an L1 cache on the node that's servicing the session to improve read performance.

The session ownership system discussed in EJBTHREE-2051 can be used to detect failover and the need to invalidate the session out of L1. The locking system should return whether the call required obtaining the lock from a remote node; if yes that implies failover and an invalid L1.
