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

Reviewers: mp+244772_code.launchpad.net,

Message:
Please take a look.

Description:
Use both credentials to connect to Juju.

Use both the user name and password when connecting
to the Juju WebSocket API.

Update the jenv models to reflect what we expect to
find in the jenv file.

QA:
- use quickstart as usual
   (.venv/bin/python juju-quickstart ...);
- the user is now printed to stdout;
- the environment and the GUI log in correctly,
   in the case the environment is bootstrapped by
   quickstart or already there.
