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 don't have a link. I'm suggesting that the bullet point look like this:

> Use single quotes instead of double quotes whenever possible. Single quotes are less visually noisy than double quotes, and they are easier to type.

Shazam. Now we've told the user both what the policy is and why the policy is in place.
