Code review comment for lp:~frankban/juju-quickstart/code-reorg

Reviewers: mp+241416_code.launchpad.net,

Message:
Please take a look.

Description:
Code reorganization + docs.

Reorganize the jenv related code in preparation of the
bootstrap strategy change.

Separate jenv handling from the environments.yaml file
management in models.

As a consequence of only supporting juju >= 1.18 we
can now safely always retrieve the admin-secret from
the jenv file.

Also updated the HACKING docs to include a brief
description of the project structure.

Tests: `make check`.

QA: use quickstart as usual.
