MODE-1763 Changed from using deprecated methods (compatible with 5.1.x) to the newer 5.2.x style configuration builders.
MODE-1834 Corrected federation logic when pessimistic locking is enabled

When Infinispan's PESSIMISTIC locking mode is enabled, ModeShape failed
to properly create and remove federation projections.
This is because PESSIMISTIC mode apparently requires explicit transactions.

Recent changes to upgrade to Infinispan 5.2 and change over to the newer
configuration builder API causes some of these problems to be exposed.
These tests run fine again after the projection management logic was fixed.
MODE-1771 Removed the ISPN 5.1-specific cache settings

Now that we've moved to Infinispan 5.2, this commit removes the
5.1-specific settings and logic that was recently added to the
Schematic framework.

Also adjusted several clustering tests so that the repositories are
cleaned up with a slight delay so that repositories are not shutdown
when they are processing the JGroups view changes from another
repository shutting down.
