Review request for mesos, Gilbert Song, Jason Lai, and Jie Yu.

Bugs: MESOS-6893

Repository: mesos


This patch added the following capabilities:
1. add the size and fetch timestamp of each docker image layer in metadata;
2. checkpoint and recover size (timestamp will be added later);
3. reuse the `DiskUsageCollector` class to track size of each downloaded store;
4. for upgrade path, reuse same collector to back fill the size of layers.

Tests to be added later. Sending out review for earlier feedback.
