Implement LongRebootBlockingReported metric

Adds a new BlockingEntityRecord class which tracks a
component or app uid which is blocking the reboot. If a
given component/app block the reboot for a time greater than
a given threshold (default is one hour), this will be logged
to statsd with a LongRebootBlockingReported atom. This atom
may be logged multiple times if the entity continues to
block the reboot for multiple thresholds. The threshold
is configurable via DeviceConfig.

Maps of blocking components/apps are stored in RebootReadinessLogger. If
a previously blocking app/component is no longer blocking the
reboot, it will be pruned from the map.

Test: Manual. Configure DeviceConfig and test with a blocking
      app and component and a threshold of 10 seconds. Note that
      the correct data is written to logcat when the reboot has been
      blocked for 10 seconds.
