E2E tests for count metric partial config update

End to end tests for partial config update for count metrics.
Creates one count metric that counts syncs while the screen is on and
the uid doing the sync is holding a wakelock, slicing by the uid's
process state. This metric gets persisted.
It is paired with simpler metrics for testing changes and
additions/removals.

Also add a gitignore.
