Development: Investigate how to handle our own backend configs

[guttenberger]

We should have one file describing the configuration of our backend. This file should work with our docker compose file and our server. Maybe using environment variables?

example configs:

• db connection string / user data
• what file types are allowed to be uploaded to our db (we cant allow all filetypes)
• staging environment (development or production)
• port of our app

@guttenberger what would change for the different environment variables?

[Fr3574]

@guttenberger and what do you mean by filetypes?

[guttenberger]

what would change for the different environment variables? currently nothing, later maybe if we use s3 or google cloud storage, we will have different dbs stings for testing and production, i think

what do you mean by filetypes? i think it is a best pratice to restrict upload file types that we know will work with our backend. Your current pr does support that so that we don't need to worry about that now.

i.g. filetypes :

• NetCDF
• pdf
• .mp3
