surround returned query in CDATA to prevent parsing of xml within xml

In migrating to Hazelcast 2.4.x, replace deprecated methods. Use Hazelcast.newHazelcastInstance() rather than Hazelcast.init(). For other deprecated static methods, use the HazelcastInstance equivalent calls.

In CNodeService.updateReplicationMetadata(), we are setting the replicaVerifiedDate() when we update or wholesale add a new replica. However, in setReplicationStatus(), we only do so when there's a new entry. Change setReplicationStatus() to also update the replicaVerifiedDate on updates of existing entries to be more consistent with other changes. This affects node prioritization based on this date timestamp. Thanks to Skye for pointing this out.

To attempt to address performance and stability WRT Hazelcast communication, we're upgrading to the 2.x series of Hazelcast. remove the 1.9.x jar files, and add the 2.4.1-SNAPSHOT jars. Modify HazelcastService to handle the minor change in the ItemListener interface (now passes ItemEvent<Identifier> as an argument)....

implement query description for pathquery -- only tells callers about the pre-indexed paths we have in Metacat since there are an infinite number of "fields" when storing arbitrary XML, but we really don't want people using non-indexed paths for performance reasons anyway. I've typed all the fields as String, even though some are not just strings and can be used for numeric or data comparisons.
