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 
Can you add some background to this point? I think it's beneficial to say why a given policy has been established. Otherwise, the policies we come up with will just seem arbitrary and annoying.
