* I've moved the example secure directory to playbooks/secure_example,
  the directory structure in your secure repo should mirror that in
  secure_example/
* If you run the lms role without a valid git-identity file it will
  fail, there is an empty file checked into the secure_example dir
* Using GIT_SSH env for git checkout, we will also need to use that
  for pip installs that use git if there are private repos in
  requirements.

* Created new directory structure outlined in the README
* Created the LMS role which for now just creates teh application config
files
* Created the common role
* Updated the cf playbook to accept arguments
