Bertrand SIMONNET 9d3a4aeae2 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.

Bertrand SIMONNET a5b40d077f metricsd: Don't cache the metrics status in the daemon.
metrics_daemon should never get a stale answer on whether or not the
metrics are enabled.
This is important as metrics_daemon will be the "source of truth" for
other components.

Bertrand SIMONNET 3598d951a6 metricsd: Fix race condition in the tests.
We cached the enabled status for metrics as a static field in the
metrics library. This field is not reset in between tests which treats
the metrics as enabled if they were enabled previously.

None of the users rely on the caching being static so the cached status
was changed into a field.
Also enabled the metrics in upload_service_test.cc after verifying that
the test failed consistently.

Bertrand SIMONNET 2765d0abcc metricsd: Use the metrics directory everywhere.
Instead of passing different filenames around, only rely on the metrics
directory and infer the filepath from it. This makes testing easier.

Bertrand SIMONNET 1253186728 metricsd: Make the unit tests pass.
This cleans up the unit tests and update them to pass.

Cleaned up:
* removed the irrelevant bits.
* Used ScopedTempDir for all test specific files (instead of the current
  directory).
* Update some objects to make them more easily testable.
* Group all the test in a single binary and use bionic's test runner.

Bertrand SIMONNET 52e5b99983 metricsd: Relicense as Apache 2.
MODULE_LICENSE_BSD and NOTICE were removed as the license is no longer
different from the rest of system/core.

Bertrand SIMONNET da21ac0751 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.
