What should we build?

We would like to somehow be able to define certain fields to be sensitive. For example BGP passwords do not need to be visible in plain at all times.

It would be cool to have them visually represented with *** in the GUI with the option to de-mask with a click of a button. This probably makes it mostly a GUI feature request, please move this issue there if necessary.

Relevant pseudo code
