We want to be able to use github apps to centralise circle ci config for some of our deployments so its easy to propagate changes to the pipelines and avoid copy pasting the same pipeline in multiple repo's. However, we also want to restrict access to contexts such as our prod deploy context for this group of services but GitHub app based pipelines don't support this in their current state. The ability to restrict context access via security groups is a vital piece of the puzzle as we don't want ALL members of our GitHub org accessing these contexts
