As a DevOps Engineer, I want to add manual approval points in my pipeline so that the pipeline pauses at that point and waits for a manual approval before continuing execution. Manual approvals are commonly used for approving deploying to production or modeling activities that are not automated (e.g. manual testing) in the pipeline.

Acceptance Criteria

• User defines a manual approval point into their pipeline
• PipelineRuns for user's pipeline pause at the point where manual approval is defined and waits for approval
• Once user approves the PipelineRun, the PipelineRun continues execution
