[PATCH v5 0/3] Yocto Gitlab CI

[Bertrand Marquis <bertrand.marquis@xxxxxxx>]

This patch series is a first attempt to check if we could use Yocto in
gitlab ci to build and run xen on qemu for arm, arm64 and x86.

The first patch is introducing a container template from which container
files can be generated for all combinations we want to support (qemu
arm, arm64 and x86 targets and hosts x86_64 and arm64).
It is also introducing a generic build script (build-yocto.sh) that is
used to create, build and run a Yocto project.

The second patch is adding a way to easily clean locally created
containers.

The third patch is introducing some gitlab CI templates and jobs so that
we can test a Xen source tree in gitlab-CI using Yocto.

This has been tested on a x86 host machine and on an arm host machine
(with mk_dsdt.c fix).

Changes in v5:
- automatic cleanup of generated docker files using INTERMEDIATE
- typo fixes
- rebase on Stefano's next branch
- remove clean rule cleaning all containers

Changes in v4:
- rework the container generation to support multiple hosts
- rework the container generation to use a single template for all
  docker files (make process is generating the docker files).

Changes in v3:
- limit number of jobs in yocto
- do not copy build script inside container
- add patch from Michal to create gitlab jobs

Changes in v2:
- remove gitignore patch which was merged
- add a --dump-log support in build-yocto.sh script and use it during
  container creation to see the error logs.
