title: Trigger one repo ci inside another repo
body: <p>I have two repos under the same organization on github that depend on each other. Repo B is a submodule in Repo A and I would like to run Repo A's azure.yml against any pull requests to repo B. I want a pull request to B to essentially clone A and replace the submodule and run the pipeline for A and report the results back to B. Is there any way to accomplish this?</p>
