yaml config structure

[snork-alt]

Let's create a separate root section for the doer-config.yaml called settings.

This should include the sub-sections api and app, and we should distribute each setting and flag under its own section. No configuration settings should be at root level. Thus, the general structure of the yaml file should be:

• app_name
• connections
• sources
• sql
• endpoints
• settings
  • app
  • api

We'll still have cloud at the root and telemetry should go into settings?
