Add initial support for vagrant.

run:
rake r10k:install
cd tools/vagrant
vagrant up
vagrant ssh mcomaster
mcomaster$mco ping
mcomaster$sudo -s
mcomaster$RAILS_ENV=production scl enable ruby193 "/usr/share/mcomaster/bin/rails server -p 8080 "

Now open in your webbrowser http://localhost:8080, and can login using the username vagrant@example.com
password vagrant
You will have all three machines configured,
middleware (activemq and redis), mcserver (one
server to test mcollective) and mcomaster (the mcollective
client with mcomaster.

TODO:
Make sure the mcomaster puppet module provides a initscript
and configures the mcomaster service.
Make mcomaster puppet module install mco from source.
