ACCUMULO-2789 Fix error handling max column qualifier length. It was using the values for
the column family size.

> Add a system test that allows stress testing an Accumulo instance in the presence of
large cells and rows.
> The test should run a configurable number of ingest and reading clients and allow setting:
> * configurable range of overall key size
> * configurable range of key component sizes
> * configurable value size
> * configurable number of cells per row
> * optional use of isolation on server and/or client
> This kind of test would help us preemptively find issues like ACCUMULO-2671, ACCUMULO-201,
and the tserver memory crashes observed with some large mutation sizes while working on YCSB
support for Accumulo.
> It will also help us provide test examples of supporting large cardinality on rowids,
column families, and visibilities.
