UI: Add approval job queue
Help open source maintainers and deployment managers by giving a view of all pipelines currently on-hold awaiting approval.
With the addition of secured context an actor can approve a job from a developer for deployment or allow an open-source PR to access contexts for testing after being reviewed.
What would be useful for those actors is a view showing a queue of items they have the ability to approve. Ideally, this view would contain a list of pipelines that the actor follows which are on hold.
It would be beneficial if there was a visual indicator that affirmed if the actor has access to all of the required contexts in that pipeline or if it needs to be approved by someone else.
