This set of commits adds a new library for OVS that allows for measuring
the performance of operations in OVS and compiling statistics from these
measurements.

The aims of this addition are twofold:
1) For developers, this can provide a measurement of something that is
either finer or coarser-grained than what is easily measured with a
profiler.
2) For admins, the statistics in the database can serve as a method of
alerting that systems are under stress and action should be taken to
ease things.

Mark Michelson (3):
  Add performance measuring API
  Save performance stats to database.
  Measure performance of ovn-controller loop.
