Add production settings

[jusjayson]

A user shouldn't be able to hack our project INTO THE GROUND

Purpose

Our keys/secrets, allowed hosts, etc should be obscured into an env/gitlab ci for production.

Functionality

Description

Sensitive settings (i.e., DB password, DJANGO secret key, etc) should be obscured into the following

• Gitlab project variables
• In local dev, a common default can be used due to low security concerns

Affects: Where will this change?

• This will change production. We'll need to obscure keys from our builds using something like gitlab file vars.
