New description:

 There are various moving parts to the buildbot master, and it would be
 nice to know how well they're performing on a running master.

 Some examples:
  * Cache hit rates
  * Time spent in scheduler loop
  * Time spent in builder loop
  * # builds or steps starting per unit time

Comment(by dustin):

 Users should be able to add their own metrics, too.

 There should be a simple interface for querying these metrics, e.g.,
 {{{self.master.metrics.getMetric(metricname)}}}

 Metrics will need to be able to sustain themselves over master restarts
 and reconfigs.  I've been thinking of making {{{scheduler_state}}} into a
 more generic saved_state (owner, key, value) store, which would allow this
 sort of state storage without new db tables.

 Are metrics per-master, or clusterwide?
