Add feedback that environments are being cleaned up
Problem
In the MVC proposal of Provide a mechanism to clean up stale environments (#19724 - closed), we omitted adding any UI feedback to show users that environments were being cleaned up. This was done to keep the scope small for a first iteration. As we have seen in the past, users prefer to have feedback shown in the UI that an action has been successful. To improve this feature, we should add feedback that the action had been taken successfully.
Example issues around UI feedback:
- Give users more feedback when they have success... (#378924 - closed)
- Users should receive feedback when they approve... (#388281 - closed)
Proposal
Add a banner or alert to the page when users have taken an action to clean up environments. This banner could either show the progress of the cleanup, or simply confirm to users that the action had been successfully taken.
