Implement a script to generate Puppetfile

* Implement generate_puppetfile.sh
This script will read from openstack_modules.txt and
external_modules.txt that contain the list of Puppet modules we rely to
run our CI. It will build a Puppetfile by using master for Puppet
OpenStack modules and the latest tag for external modules.

* Remove Puppetfile, that is not useful anymore since it's generated.

* Run the script everytime our CI needs to install modules.
Which means our CI will always test the latests versions of our external
modules.

* Allow to pin modules.
Example:
puppetlabs/puppetlabs-apache,1.8.1
