Review request for accumulo and Mike Drob.

Bugs: ACCUMULO-2899

Repository: accumulo


Make sure that we behave correctly when our cluster has been upgraded 1.4 -> 1.5 ->

* dfsloggers need to track the cq used to create them so they can be used to issue putDeletes
* rewrite 1.4 WAL paths to the top level wal directory
* adjust recovery path to compensate for 1.4 recovered wals
* fix GC to properly handle upgraded WALs
