Updated quickstart dependencies for utopic.

Updated quickstart dependencies for utopic.

Quickstart now uses the dependency versions we
expect to be available in utopic.

Update the code parts in which quickstart interacts
with the juju client and the websocket Python
libraries: ensure we only log the textual WebSocket
messages we are interested in.

Also remove the deprecated --use-mirrors pip option.

Tests: `make check`

QA:
Use quickstart as usual to bootstrap local, ec2 and HP
environments: `.venv/bin/python juju-quickstart -e ...`
