Create Augur collection Config file #3301
Description
Is your feature request related to a problem? If so, please describe the problem:
Because there are config values hardcoded into augur/application/config.py which are written to the database at startup by default, the easiest path for making any changes to these values is to rebuild the docker container.
Changing the values in the database is not viable because they get rewritten with each startup of the application.
Potential solutions:
I think there should be a way to supply this config via a file. By reading the file at startup (if present) before relying on hardcoded values, config is able to be changed simply by restarting augur, rather than doing a full rebuild to patch the hardcoded values.
