Create security group for RDS

[wazcov]

At the moment we have to manually edit the VPC group to allow all ports for the code to run. This can be done programatically

I looked at the code and would like to suggest something: instead of creating resources(infrastructure) programatically you could use terraform or cloudformation. I'm up for adding this to the repo if you want.

That would be a cool addition, I think different people may have different use-cases meaning both Java programatical examples and cloudformation examples for achieving the same task would be beneficial in the same repo. Feel free to add and create a PR

I'll create a PR ;-)
