As an eZ Platform maintainer, I want eZ Platform admin UI pull-requests deployed to Platform.sh so that I can test them.

The code should be deployed only when all the other tests passed. GRD should report to the pull-request with the platform.sh instance URI (are those public ? does it mean anybody can access them ?)

Ideas for later, to keep in mind

GRD could get notified from the start, and add a message to the PR saying that it will start when other tests have passed. Then we could add a button to it to force start the deployment.
