Jesse Keating 0bd80421d4 Fix up docs and add ability to insert files 
Files can be inserted during server creation (like a fully formed

Docs were updated for formatting, location, and to add the new entry for
files.

examples:
- code: 'local_action: rax creds_file=~/.raxpub service=cloudservers name=rax-test1 flavor=5 image=b11d9567-e412-4255-96b9-bd63ab23bcfe wait=yes state=present'
description: "Examples from Ansible Playbooks"
requirements: [ "pyrax" ]
author: Jesse Keating
notes:
- Two environment variables can be used, RAX_CREDS and RAX_REGION.
- RAX_CREDS points to a credentials file appropriate for pyrax
- RAX_REGION defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
