Add approval in wait task

[FogDong]

Feature request

Right now we have our wait task to support starting the task after a time, but can we start the task after some specific action like approval?
In my case, there's some situation that the task needs to be approved by the admin before it gets executed. So before the admin approves the step, the task needs to be paused.

Use case

ref tektoncd/pipeline#3796

As a simple mechanism for implementing approval, you could create a controller that just waits forever for an Approval-type Run (i.e., doesn't reconcile or take any action), and expects some other system to update its status to Done once approval is granted.

That other system could be an HTTP endpoint, an email/SMS/Slack receiver, etc., with permission to update the Run status.

You could also express rejection of approval by setting the status to Failed, track the identity of the approver in the Run status, implement expiring approvals by reintroducing some wait logic from the wait-task, etc.

So we don't want to have approval in the wait task, and prefer to let users implement it themselves? 🤔

During CI/CD in DevOps Workflow there should be Release Manager Approval workflow. Isn`t a standard in any DevOps CI/CD Pipeline.
