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 
Anyone else care to comment on this point? Do we want to set a specific policy on this? Personally, I pack all imports together and sort them alphabetically, but I'm willing to change if folks think there's a strong readability advantage to this approach.
