Jon: This is not a refresh metrics per se. Its for defining what a user
considers to be a _longer_ period for a Region to be in a transition state, and
show these regions count as a metric.
So, it can be hbase.metrics.rit.stuck.warning.threshold?
Long name, though. Please let me know amd I will change accordingly and
revise the patch.
