Bundle "Deploy via deployer" should recommend juju-deployer package

[Marco Ceppi]

Current deploy readme is quite indimidating and doesn't set up juju-deployer from the package, which would be preferable (like juju-quickstart)

Currently, it recommends:

Step 1 - Setup the virtual environment

virtualenv --system-site-packages deployer
./deployer/bin/easy_install juju-deployer
./deployer/bin/juju-deployer -h

Step 2 - Deploy bundle

./deployer/bin/juju-deployer -e <JUJU_ENV> -c \

Instead these could be

Step 1 - Install Juju Deployer

sudo add-apt-repository ppa:juju/stable
sudo apt-get update
sudo apt-get install juju-deployer

Step 2 - Deploy bundle

juju deployer -e <JUJU_ENV> -c http://staging.jujucharms.com/bundle/~jorge/cloudfoundry/3/cloudfoundry/json
