v5:
 - Remove Signed-off from Sami (I replaced it with Co-authored-by)
   [Leif]
 - Update edk2 submodule to latest master. [Pierre]
v4:

   get the PatchCheck.py script. [Pierre]
v3:
 - Replace Readme(s)'s by a reference to the initial Readmed(s) in
   tianocore repository. [Sean]
 - Align CI files with the latest version in the edk2 repository.
   [Sean/Michael]
 - Add additional step to checkout edk2's latest master in the CI.

v2:
 - Use tianocore repository instead of personal repository
   for edk2 submodule [Pierre]

It provides the configuration files necessary to run an upstream CI
similar to the one currently used for the main edk2 repository. The
configuration is mostly similar aswell.
Enabling the CI requires administrator rights on the edk2-platforms
repository. This configuration was tested on a private repository,
but will require additional configuration from the administrator.

CI plugins (.pytool/Plugin/) and BaseTools are located in the
Tianocore edk2 repository. To re-use them, add the edk2 repository
as an external dependency.
It is not currently possible to specify a branch name in the "version"
field. Thus, a fixed commit hash (current edk2 master) is written.
It will eventually be replaced by 'master'.
If a platform requires a specific version of edk2, another description
of the edk2 repository in the edk2_ext_dep.yaml can be added. Only the
edk2 repository with the right scope will be installed.
It is possible to use a custom edk2 repository instead. To do so, run
the stuart_[update|build] commands with EDK2_REPO pointing to your
custom edk2 repository.

Compared to edk2's CI, some steps are modified and indicated by
EDK2_PLATFORMS_MODIF_[START|END] statements.
