This commit renames the variables, functions used in confirm_dialog.js
and classes and ids used in confirm_dialog.hbs.
This change is made so that we can easily migrate edit_fields_modal to
use this same code with some more changes.
We will change the file names and correspondingly import variables in
the next commit.
This commit renames confirm_dialog_yes_button class to
confirm_dialog_submit_button. This will help in keeping
a general class name when deduplicating the code for
confirm_dialog and edit_fields_modal.
We show a spinner inside the button instead of hiding the button
and then showing the spinner in the bottom area. We also disable
the button to avoid repetitive clicking by user.
The only downside of this is that it makes it harder to control the
order of these tests; which isn't that important. And the structure
of naming each with its test order fundamentally requires renaming
files when adding/deleting tests, so if we want to control the default
test order, we'd be better off doing that by just hardcoding a list in
the test runner code.
