Description

Currently we have a section of the manual titled "Most Important RegionServer Metrics" but all it says is:

Previously, this section contained a list of the most important RegionServer metrics. However, the list was extremely out of date. In some cases, the name of a given metric has changed. In other cases, the metric seems to no longer be exposed. An effort is underway to create automatic documentation for each metric based upon information pulled from its implementation

In the meantime, let's continue to maintain a list of operationally useful metrics.
