Add support for build volumes

[yajo]

docker build supports the --volume option to add volumes at build time.

docker-compose does not have such support (or it is not docummented).

AFAIK, only Red Hat's fork of Docker Engine support it:
https://github.com/projectatomic/docker/tree/docker-17.03.1-ce#add-volume-support-to-docker-buildpatch
moby/moby#14080

So I doubt @shin- will add it.

Note that besides moby (see: moby/moby#14080), docker-py is lacking support for this as well (see: docker/docker-py#1498).

I suggest to no accept my above PR #5736 till docker-py (e.g. via PR docker/docker-py#1937) has support for build time volumes.

Closing alongside #5736 docker/docker-py#1937 etc. Per docker/docker-py#1937 (comment) this is supported differently in buildkit and I don't believe that approach needs tools level changes to support. Building with buildkit from compose is already tracked elsewhere I believe.
