The new ConfirmationOverlay object along with the
BaseView.ask_confirmation helper can be used to open a confirmation
dialog and get back the decision from the user.

Attempting to close an overlay that does not exist is pretty much always
a bug in the code. Making not_found_ok true by default will hide obvious
bugs from us ; which is not a good thing. Perhaps more importantly, we
might just remove the wrong overlay.
Instead, we should just pass not_found_ok=True as a workaround when we
know the code is buggy and don't have time to fix the bug cleanly.
This is what happens for SSH keys import. If the import fails, we remove
the loading animation. However for answers-based runs, we do not have a
loading animation so the code bails. Let's add not_found_ok=True in this
context and we can fix the code later.

BaseView.remove_overlay() would crash with AttributeError if no overlay
was found. We now add a not_found_ok parameter (defaulting to True) that
makes the function silently return if the overlay could not be found.
Passing not_found_ok=False and catching OverlayNotFoundError can be
helpful in some scenarios to do something different if no overlay was
found.
