backport of #1484 for 19.03

The aufs storage driver is deprecated in favor of overlay2, and will
be removed in a future release. Users of the aufs storage driver are
recommended to migrate to a different storage driver, such as overlay2, which
is now the default storage driver.

The aufs storage driver facilitates running Docker on distros that have no
support for OverlayFS, such as Ubuntu 14.04 LTS, which originally shipped with
a 3.14 kernel.

Now that Ubuntu 14.04 is no longer a supported distro for Docker, and overlay2
is available to all supported distros (as they are either on kernel 4.x, or have
support for multiple lowerdirs backported), there is no reason to continue
maintenance of the aufs storage driver.
