/*
Look for confirm_dialog in settings_user_groups
to see an example of how to use this widget. It's
pretty simple to use!
Some things to note:
1) We create DOM on the fly, and we remove
the DOM once it's closed.
2) We attach the DOM for the modal to conf.parent,
and this temporary DOM location will influence
how styles work.
3) The cancel button is driven by bootstrap.js.
4) For settings, we have a click handler in settings.js
that will close the dialog via overlays.close_active_modal.
5) We assume that since this is a modal, you will
only ever have one confirm dialog active at any
time.
6) If a modal wants a loading spinner, it should pass loading_spinner: true.
This will show a loading spinner when the yes button is clicked.
The caller is responsible for calling hide_confirm_dialog_spinner()
to hide the spinner in both success and error handlers.
