Refactor the metrics client slightly to add the concept of a "reporter" that actually sends the metrics. The primary implementation is HTTP-based as before, but a key difference now is that there's another variant that writes to a file for simplified debugging. This is activated by setting the `DOCKER_METRICS_DEBUG_LOG` environment variable to a file path to write events to as JSON lines. Signed-off-by: Milas Bowman <milas.bowman@docker.com>
