Review request for mesos and Qian Zhang.
Changes
-------
Added a comment for the pull hashmap; fixed indentation.
Bugs: MESOS-10169
https://issues.apache.org/jira/browse/MESOS-10169
Repository: mesos
Description
-------
This patch makes the docker store reuse a pending pull if asked for
an image that is already being pulled.
The pull caching follows the same approach as the earlier attempt in
https://reviews.apache.org/r/39331 . However, handing out futures to
the store callers and handling their discards are performed differently,
using a form of reference counting, so that the pull itself is discarded
only if all the futures returned by `Store::get()` have been discarded.
