Code review comment for lp:~frankban/juju-quickstart/jenv-env

QA - OK

I was surprised to see the username printed as 'user-bac' (because I
hadn't noticed that part of the code).

Why do we have the user- prefix? Is that a juju-gui thing?

I don't think we should make that user visible, i.e. don't print 'user-'
when showing the credentials being used. The prefix does not appear in
the .jenv file or 'juju user list'.
