Currently we have a mix of casenames in the server.yaml.

the JWT settings are capitalized, and the rest of things are all lowercased. [0]
Django requires all settings to be uppercase [1], we do that right now by converting the settings to uppercase on load time [2]

Personally I've not seen any yaml file with UPPERCASE settings so that might be unconventional, and what we're doing might be the right thing. In any case we should standardize our config names, whether through lowercasing the JWT configs, or capitalizing the rest of the settings
