Added monitor activity page for Fate transaction details

I was looking at the Bulk Import page on the monitor, and I'm not sure that we will be able to show that level of detail going forward. That information is serialized in an object in the Fate transaction for the Bulk Import. Getting access to the serialized object requires that we reserve the Fate transaction, which we can't do if it's currently executing.

As a possible replacement for the Bulk Import page, this page shows the status of All Fate transactions (not just Bulk Import). It displays a lot of the same information as the command accumulo inst fate list.

IIRC the held and waiting locks are the namespace id or table id. The lock range is the prevEndRow and endRow, so they might need to be obfuscated.
