Customize configuration files through configmaps (routr-connect Helm chart)

[alvitoraidhy]

Is your feature request related to a problem? Please describe.
We're looking to deploy this as a subchart with another one containing Asterisk instances. Ideally this would be pre-configured as in once deployed Routr would loadbalance the asterisk instances automatically. However as far as I understand we need to add peers through the CLI first after deploying.

Describe the solution you'd like
If we could have parameters to define peers, credentials, etc I think they would be great additions to the chart.

Describe alternatives you've considered

I'm converting this into a conversation. Although I believe we can improve the process of seeding the database, I don't think it belongs in the Helm chart. Perhaps we could introduce a command for rctl to seed the DB from a JSON file?
