newer d1 jars -- contains CN.isNodeAuthorized() method

collect "message" param from multipart request for MN.synchronizationFailed method

Reverting previous @Overrides chanrge from r6470, as that is the desired
behavior under Java 1.6 -- previous versions of Java (e.g., 1.5) will not
comile with this usage of the @Overrides annotation, but the currently
supported version will. So reverting to the 1.6 convention.

Removing incorrect @Override annotations that were preventing compilation. The methods marked did not actually override a method in the superclass, so they were not compiling. I think @Overrides was being mistaken for methods that implement an interface but aren't actually in the superclass.

use d1_common_java's date serialization utility for parsing parameters

catch runtime exceptions that arise from hazelcast storage errors in the system metadata map

Lock the system metadata entry in hzSystemMetadata when calling setReplicationPolicy().

Lock the system metadata entry in hzSystemMetadata when calling registerSystemMetadata().

Remove references to CNReplicationTask.

Remove the CNReplicationTask (for now). We will be using Metacat's ForceReplicationHandler to replicate science metadata across CNs, and may explore the use of a 100% evicted hzScienceMetadata map. Either way, the distributed task design won't be needed. When a dropped CN comes back online, we'll catch it up based on last modified dates for PIDs in the hzSystemMetadata map.
