Message:

OmeroClustering : Moving away from jgroups to straight multicast/jdbc approach

The ReplicatedHashMap implementation used from the org.jgroups.blocks
package had issues with our usage of the map. Since we are already
guaranteed a share storage (the db) for all blitz instances within
a single cluster, we are now using Ice's multicast support (from 3.3)
as well as simpleJdbcTemplate to manage the same information that was
previously in jgroups.
(cherry-pick from commit e50eed4204c2a1d360c2b261b5e6a7618573ba65)
