Ansible modules snippets for snipmate.vim

I made a small script, to generate a snippet file for snipmate.vim to help
fill playbook and find the parameters to this module.

Hi, please be advised that there some pending changes in the
module_formatting stuff -- the get_docstring() is moving to ansible
utils as soon as pull-request #1582 has been merged.

Just FYI in case this breaks your code, which we don't want to happen.
Do keep an eye out at https://github.com/ansible/ansible/pull/1582
