DDF-905 Changing format of configuration passwords to match web console.

Right now the web console passwords for configuration, if there is no password, will show a default password of 'unmodified'. The admin UI previously showed nothing. Now if there is no password, we'll also so the 'unmodified' password. These passwords are hidden of course.
@beyelerb looked it how it works in the web console a couple years ago, but in the web console I believe it actually looks for the phrase and will take it out of the map (string) that it sends back to the configuration. Just an FYI for you to compare the functionality with the web console.
