ACCUMULO-2488 Change criteria for unbalanced servers in concurrent randomwalk

The Concurrent randomwalk test used to consider servers unbalanced if any server's
tablet count differed from the cluster average by more than a fifth of the average or
by one, whichever was larger. This would cause failures under typical balancings from
the default balancer.

This commit changes the criterion for an unbalanced server to be double the standard
deviation from the cluster average.

ACCUMULO-2491 Correct table user state upon termination of Security randomwalk

A partial backport of ACCUMULO-1162 to 1.4 - commit e93a11a only. As the Security randomwalk
ends and drops the table user, it now also sets the user's existence flag to false.
