According to my measurements MutableIndexSplitForwardScanIT used to run for
about 11 min 40 sec, now it is 2 minutes 40 sec (on my Computer).
We gain the same amount of time at MutableIndexSplitReverseScanIT.
This change reduces the test runtime by (around) 18 minutes.

Thanks for digging into this, Richard! I'm curious because I see some pretty
drastically different results than you:

This was the test execution time for me running on commit
e1aee8e5d3fe335450db583f01cf91af1e6c5c7e with the command:
{noformat}
mvn clean verify -Dtest=foo

>
> Some tests take a long time to run not because they are
> computationally/memory/IO intensive, but simply because they are waiting for
> some HBase chore to be run.
> One such test is MutableIndexSplitIT where we must wait for
> CompactedHFilesDischarger for the requested split to happen.
> Try to identify these cases, and reduce the chore intervals in the
> MiniCluster setup to speed up test executions.
