Add explicit vocabulary to the interactive refactoring operations to inform the user about the action being interactive

Today, the refactoring jobs are interactive (rename, especially), even after the progress bar starts to advance (a question without a timeout can arrive at any point - such as an overwrite question).

However, nothing in the UI says explicitly to the user that they need to keep an eye on the operation until the progress bar gets to 100% and not close the tab / window. We should make it more obvious in the UI.

This can very easily result in XWIKI-19728 , from a user that closes the tab thinking that the job is done.
