Skip deploy to review app if MR is set to MWPS
Problem to solve
When creating an MR that is quickly set to merge automatically when the pipeline succeeds, we can speed up that pipeline slightly by cutting out unnecessary steps. Specifically, deploying to a review app is completely unnecessary if the MR is just going to be merged immediately (and the review app deleted).
Identify jobs related to temporary deployments, and skip them when the MR is set to MWPS. We could possibly require the user to manually identify these jobs, but we can probably infer well enough to not need manual identification.
