Add StatsdStats and guardrail.

+ StatsdStats is the global class that tracks the stats about statsd.

+ Added guardrail for classes that have a map which could potentially grow
  unboundedly with the number of logs.

TODO: add unit tests & CTS for StatsdStats, and guardrail
      add stats for pulled atoms.

Test: statsd_test
