Metacat

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.

Change isNodeAuthorized() to query the hzSystemMetadata map rather than the hzPendingreplicationTasks map. The latter isn't needed for authorization since the ReplicationStatus for each Replica in SystemMetadata lists the status of the replica and can be queried.

Add getNodesMap() to return the hzNodes map from the process cluster. Remove getPendingReplicationTasks since that structure is being removed. Add minor documentation.

Set the correct cluster name and password for the D1 Hazelcast process cluster. This will likely change for production deployments.

only include 0.6.4 schemas for D1. Will also need to update this when we release whatever v1 ends up being.
