ci: add README and makefile for containers

Add a basic README explaining the containers and how people can use them
to locally test with if they see an error in CI and want to reproduce it
locally. Added a makefile to help with building and pushing the
containers to the container registry.

+Docker Containers
+=================
+
+These Docker containers should make it possible to build Xen in
+any of the available environments on any system that supports
+running Docker. They are organized by distro and tagged with
+the version of that distro. They are available from the GitLab
+Container Registry under the Xen project at:
+
+registry.gitlab.com/xen-project/xen/DISTRO:VERSION
+
+To see the list of available containers run `make` in this
+directory. You will have to replace the `/` with a `:` to use
+them.
+
+Building Xen
+------------
+
+From the top level of the source tree it should be possible to
+run the following:
+
+docker run --rm -it -v $(PWD):/build -u $(id -u) -e CC=gcc $(CONTAINER) make
+
+There are other modifications that can be made but this will run
+the `make` command inside the specified container. It will use your
+currently checked out source tree to build with, ensure that file
+permissions remain consistent and clean up after itself.
+
+Building a container
+--------------------
+
+There is a makefile to make this process easier. You should be
+able to run `make DISTRO/VERSION` to have Docker build the container
+for you.
