Cloudformation template for security monkey

I'm not really expecting this to be merged without further work, but I've been attempted to produce a cloud formation template for security monkey that is more production like.

This seems to work at the moment, although it needs a little more work around:
 - FQDN configuration
 - documentation (manual steps before and after - mostly how to configure the roles)
 - not having the default git repo be the guardian fork

Let me know if you are at all interested in merging this - if so I can do some more work towards making it generic (comments welcome - especially based on how you run it in production). Otherwise I'll carry on solo for our purposes only.
