Cleanup a variety of metric issues. * Eliminate department of redundancy "count_total" naming. * Use the plural of the unit when appropriate. (ex, "requests") * Remove label names from metric names where appropriate. (ex, "rcode") * Simplify request metrics by consolidating type label in to the base request counter. * Re-generate man pages.
