metricsd: Persist metrics on shutdown.
When metricsd receives a SIGTERM signal (on system shutdown for
example), save the metrics to disk before exiting.
Bug: 26184202
Test: Start metricsd. Log a metric sample. Stop metricsd. The metric is
saved to disk.

metricsd: Persist the metrics to disk periodically.
Every now and then (5 minutes by default), the uploader will persist the
current metrics to disk to avoid losing them in case we exit
unexpectedly (reboot or crash).
When starting up, metricsd will load the previously saved log and resume
the metrics collection from there.
Bug: 25670584
Test: Unit tests.
Test: manual: restart metricsd. The saved log is detected and parsed
correctly.
Test: manual: Send a sample to metricsd, send SIGTERM to metricsd, the
log is saved to disk, metricsd restarts and picks up the log where it
left.

metricsd: Cleanup on TERM signal.
metricsd should shutdown cleanly when receiving a TERM signal:
* stop the binder watcher.
* wait for the thread to quit.
* Exit cleanly.
Note: This is not directly used as we don't send SIGTERM on shutdown or
when stopping services yet.

metricsd: Use different directories for each daemon.
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.

metricsd: Specify directory for persistent integers.
Instead of using a global directory for persistent integers, specify the
directory to use in the constructor.
This will make changing the backing directory easier.

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.

metricsd: Persist the report to disk if an upload fails.
If the metrics server is unreachable, we may need to resend a metrics
report later. Instead of keeping the staged report in memory, save it to
disk to avoid loosing data if the system restarts or crashes.

metricsd: Rename metrics to metricsd.
This makes the import path less confusing:
* metrics/metrics_library.h is imported from the exported headers.
* metricsd/* for includes by the metrics daemon itself.
