Draf: Cross module CI

Test on the GitLab CI.

Distinguish CI for Merge Request and CI for branch.

-> If CI on branch, check if another branch with the same name exist in the dependencies module, if so pull from this branch instead of master. This will help to check unit test when developing on multiple modules.

-> If CI on Merge Request always pull from the master of dependencies. This way we make sure the CI won't break compatibility with master once merged.

TODO : When merging this we should squash commit to avoid polluting aidge backend CPU with multiple test commit !
