    METRON-569: Enrichment topology duplicates messages

    ## Contributor Comments
    This issue was discovered a while ago but a PR with a fix was never accepted.  In summary,
the JoinBolt is acking the last tuple of a split message instead of the tuple containing the
original message sent directly from the SplitBolt.  This is a problem because the tuple with
the original message is anchored in the SplitBolt and the other tuples that go to enrichment
bolts are not.
    The major change in this PR involves storing the tuples in the cache instead of just the
message.  This way the tuple from the SplitBolt can be retrieved and acked once all the parts
have been received in the JoinBolt.  
    A couple other minor changes are also included.  I refactored the JoinBoltTest to make
it easier to follow and maintain.  If anyone thinks this is worse than what we currently have
I can revert that.  I also bumped up the default cache sizes for the JoinBolts from 10,000
to 100,000.  The low initial cache size was causing failures in full dev if I let it run for
a while.
