metricsd: Split into two daemons. This CL splits metrics_daemon into two independent daemons: metricsd and metrics_collector. * metricsd will be responsible for reading the metrics from disk and periodically uploading them to the server. * metrics_collector will be responsible for gathering generic metrics from the system and managing the weave state for metrics. This refactoring is necessary to prepare the migration of metricsd to log over binder. Bug: 25670908 Test: Unit tests. Test: manual: both daemons run. Metrics are logged, uploaded and the weave interaction works.

Use specific users for metricsd/metrics_collector. /data/misc/metricsd only needs to be accessed by metricsd. /data/misc/metrics_collector only needs to be accessed by metrics_collector. /data/misc/metrics needs to be writable by metrics_collector and readable by metricsd. Make it 0750 metrics_collector:system and keep running metricsd as group 'system' to allow reading.
