Rename some metrics for more consistency:
* *.PerMinute and *.PerSecond instead of the obscur Long and Short
suffix.
* *.Percent for metrics reporting a percentage.
BUG: 24206661

This fixes three things:
* name of the metrics: the metrics does not represent the daily use.
* arithmetic error: we collect the use time in seconds so no need to
divide by 1000 to get seconds.
* the metrics should not be reset daily.
This CL also renames the Send* helper methods to be more explicit about
resetting the counters.

TEST: unit tests.

Instead of passing different filenames around, only rely on the metrics
directory and infer the filepath from it. This makes testing easier.

* converts constants static fields into proper constants.
* converts to C++/libchrome some of the parsing logic.

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.

Instead of using /etc/lsb-release to store the version, channel and
build_target_id, use the Android system properties.

MODULE_LICENSE_BSD and NOTICE were removed as the license is no longer
different from the rest of system/core.

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.
