Developers can easily execute several tests on different devices
by just pushing their branch to their fork in a repository hosted
on gitlab.freedesktop.org which has an infrastructure to run jobs
in several runners and farms with different devices.

There are also other automated tools that uprev dependencies,
monitor the infra, and so on that are already used by the Mesa
project, and we can reuse them too.

Also, store expectations about what the DRM drivers are supposed
to pass in the IGT test suite. By storing the test expectations
along with the code, we can make sure both stay in sync with each
other so we can know when a code change breaks those expectations.

Also, include a configuration file that points to the out-of-tree
CI scripts.

This will allow all contributors to drm to reuse the infrastructure
already in gitlab.freedesktop.org to test the driver on several
generations of the hardware.
