getImagesForCleanup used to query the Engine for the Supervisor
image, which is unnecessary given that the Supervisor has access
to constants.supervisorImage. Thus, this Engine query is removed.
The method is simplified and made more clear, and
imageManager.isCleanupNeeded doesn't need to be stubbed in tests.

This eliminates chances of host-Docker address collision for apps such
as the Supervisor where all services have host networking.

Also remove system interface check from ensureSupervisorNetwork.
Previously `ensure` was a Bluebird promise which wasn't awaited in
its composition step. This has been here for some time and may contribute
to issues with duplicate networks. The conversion to native Promises
allows `ensure` to be awaited, hopefully reducing instances of duplicate
networks.
Removing the system interface check for /sys/class/net/supervisor0
because it's superfluous given that the Engine creates the interface
with NetworkManager. It also makes testing a lot more difficult to set up
as /sys/class/net isn't a directory that can be written to for emulating
system interface creation / removal.

Now the tests are ran against the actual docker engine instead of
against mockerode.
The new tests actually caught a bug in
`volumeManager.removeOrphanedVolumes`, where that function would try to
remove volumes for stopped containers, causing an exception.
This commit also fixes that bug.
This also needs to modify the test environment as database migrations
will look for `config.json` in the location given by the variable
`CONFIG_MOUNT_POINT`.
The volume tests now run against the actual docker engine setup via dind
