Added rough draft of the Robottelo code standards

This is the initial draft of the Robottelo Code Standards.
I have created the format and some basic guidelines and background.
However, it will be up to the other members of the team to fill in
items that they feel are important.

This addresses #1496 
I was initially going for a list of rules, but we can add links to justify each line. It may be a bit of overkill, though.
