Support for config repo or a config file like before v0.5.0

Is your feature request related to a problem? Please describe.
I'm a dedicated NixOS user, so I love being able to reproduce services from config files 😄
Soft-serve seemed to be the perfect git server for me until I found out that the config repo got deprecated to enable the new CLI feature.

Describe the solution you'd like
Some optional config file which gets applied on e.g. the restart of the application. It contains the configuration like the users, repos, etc. Changes which were made using the CLI since the last restart of the service could be overwritten.

Describe alternatives you've considered

• Using a soft-serve version <= 0.5.0
• Writing bash scripts which configure the instance using the CLI? haha 😂
