ACCUMULO-2846 Push down the DataInputStream and immediate re-queue'ing of a file with more work to AccumuloReplicaSystem.

Handling the quick re-submission of a file with more data to replicate in the ReplicationProcessor
was a nice approach as it separated the business logic from the implementation; however, this caused
a noticable performance decrease in re-reading prefix of already replicated data from the source file.
ACCUMULO-378 Tone back logging into something a bit more useful for FinishedWorkUpdater.
ACCUMULO-2582 Add a replication-in-progress section to the monitor
ACCUMULO-2582 Use the DistributedWorkQueue to list the children instead of doing it by hand.

The DistributedWorkQueue also has a node for handling the locking of the children.
We don't want to use that, and the name of the node is not public information. So,
we should just use the queue instead of doing it by hand.
ACCUMULO-2582 Used the wrong variable in the conditional
ACCUMULO-2582 Just use the Work status instead of data in ZK
ACCUMULO-2582 Use the full path, not just the file name.
ACCUMULO-2582 Finally use the right path and add a label for non-textual data
ACCUMULO-378 Add tracing into the AccumuloReplicaSystem.
ACCUMULO-378 Try to get the tracing working for tservers sending data
ACCUMULO-2582 Use the full path to the file when we know it
ACCUMULO-2582 Get ride of the exceptions in the monitor log from trying to parse conf values we didn't want
ACCUMULO-378 More consumable label on trace data
