[MESOS-7450] Docker containerizer will leak dangling symlinks if restarted with a colon in the sandbox path

Description

The Docker CLI has a limitation, which was worked around in MESOS-1833.

TL;DR: If you launch a container with a colon (:) in the sandbox path, we will create a symlink to that path and mount that symlink into the Docker container.

However, when you restart the Mesos agent after launching a container like the above, the Docker containerizer will "forget" about the symlink and thereby not clean it up when the container exits. We will still GC the actual sandbox, but not the symlink.
