Instead of using a single directory for both the internal data of
metricsd and metrics_collector and the shared files (metrics samples log
file and the metrics enabled file), we should use separate directory to
allow for a finer access control.
The new structure will be:
* /data/misc/metrics for the files accessible to all daemons reporting
metrics, metricsd and metrics_collector.
* /data/misc/metricsd for the private files of metricsd.
* /data/misc/metrics_collector for the private files of
metrics_collector.
Bug: 25886951
Test: Unit tests.
Test: Manual: metricsd and metrics_collector run without errors.

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.
