Space deletes that will take a long time should throw a warning

Issue Summary

This is reproducible on Cloud: Yes

Steps to Reproduce

1. Delete a space (particularly a large one) to send it to the trash 
2. Go to the Trash and delete the space permanently 

Expected Results

The UI should warn the user that the space deletion could take hours or timeout and that they should instead notify support if their request is urgent. 

Actual Results

The deletion process will take a long time (hours to days) and will not notify the user of the actual progress, ETA, or whether the process is stuck. 

Workarounds

A. Allow time (up to 1-2 days) for the space deletion to complete.

B. Sometimes deleting the space using REST API will work.

• The Confluence Cloud REST API - Delete space

C. You can also check the progress of the space deletion in the long running tasks.

• The Confluence Cloud REST API - Get long-running-tasks

If this doesn't work, please reach out to support.
