Remove space permissions for any users accounts that have been removed from the site

Issue Summary

Whenever a user has permissions on a space and that user is deleted from the instance, the space permissions remain and need to be removed manually.

Steps to Reproduce

1. Assign space permission to a Confluence user
   • The user will show up under the Individual Users section of the space permission
2. Remove the user from the site

Expected Results

• Removing the user from the site should remove them from the space permission

Actual Results

• The user remains there until a space admin reviews the permissions and manually cleans it up.

Suggested Solution

Automatically remove any space permissions for users once they are removed from the site

Workaround

Manually remove those space permissions from each space after deleting the user
