Chris Weyl 5a3cfbbdf5 Allow hadolint linter to run via docker image (#720)
* Add documentation for hadolint (doc/ale-hadolint.txt)

* Allow `hadolint` linter to run via docker image

These changes enable the `hadolint` linter to run via the author's
docker image, if present.   Three modes are supported:

 * never use docker;
 * always use docker; and
 * use docker as a failback.
