Code review comment for lp:~frankban/juju-quickstart/interactive-jenvs

*** Submitted:

Display the jenv environments in interactive mode.

The jenv environments are now displayed in the
interactive session, and it's possible to use them.

Also implemented a simple jenv detail view in uwrid.

Quickstart now also supports highlighting active
environments, i.e. those that are supposed to be
running because they have a corresponding jenv file
in the juju gome.

Tests: `make check`.

QA:
user the new juju, bootstrap one or more environments
with quickstart (use .venv/bin/python juju-quickstart --upload-tools
if you are using a non-local provider).
Start the interactive session, and check those environments are
properly marked as acrive.
Run quickstart again to check it is idempotent.
Create new users and copy the resulting jenv file to
~/.juju/environments/.
Run quickstart interactive session again, and check the
new environments are reported, and it is possible to use them.
