Documentation still explaining devicemapper support although devicemapper support has been removed

[meyca]

File: storage/storagedriver/device-mapper-driver.md

That documentation should be deleted.

see Pull request docker/cli#1424

The driver is marked deprecated, which is a notice that it will be removed at some point in the future, however it's still supported

docker/for-linux#452 (comment)

At least it has been (and still is) removed in docker-ce for debian stretch... I just ran into that... :-(

Switching to overlay2 and recreating containers was a lot of work but solved the problem for me.

Regarding the referenced documentation I would at least suggest a (first?) paragraph like:

Note: As of Docker 18.09 support for Device Mapper storage driver is deprecated and will be removed in a future release (s. Deprecation Notice in Release Notes for 18.09; https://docs.docker.com/engine/release-notes/#1809).

Ah, yes, I think that was a packaging issue, not sure what the status is on that one

Regarding the referenced documentation I would at least suggest a (first?) paragraph like:

A note was added on the "Select a Storage Driver" page; https://docs.docker.com/storage/storagedriver/select-storage-driver/#docker-engine---community

But I agree that a note on the devicemapper page would be good to have; perhaps it's being worked on (there's work in progress for the legacy overlay storage driver #7803)
