Environment Variable Cleanup?

[vbhayden]

Morning team!

With ECC implementation for a few of our sandboxes coming up, I am going through and trying to simplify the deployment documentation into the barebones, "what do I need to type" instructions.

For this repo (and a few others), there are a few environment variables that seem to have just been copy / pasted from other repos but that are unused by this one:

• AWS_SECRET_ACCESS_KEY
• AWS_ACCESS_KEY_ID
• AWS_DEFAULT_REGION
• AWS_CA_BUNDLE
• REQUESTS_CA_BUNDLE

There are also a few that are used but undocumented:

• BAD_HOST
• OVERIDE_HOST

Lastly, the MySQL setup seems a bit odd, as DB_USER is used by Django but not by MySQL etc.

We can submit a PR to clean some of this up if that would help? For folks like me that skim to the meat + potatoes of setup right away, reducing environment variable intimidating is always a good thing imo.

Thanks!
