Run Increment tests that use the HBase clients; {@link TableBuilder}. Test is parameterized to
run the slow and fast increment code paths. If fast, in the @before, we do a rolling restart of
the single regionserver so that it can pick up the go fast configuration. Doing it this way
should be faster than starting/stopping a cluster per test. Test takes a long time because spin
up a cluster between each run -- ugh.
