org.purefn.kurosawa.config
Fetch configuration from the environment.
Presently, config is stored statefully in an atom after initial load.

default-configclj
(default-config)This is our default, precendence based, load config from environment mechasnism. A shallow merge was chosen to make final merged config map easier to reason about. Current precendence is:
- Environemt variables
- AWS SSM Paramter Store
- The filesystem (legacy)
Ultimately we shouldn't need this, the config stage of application/development startup needs to revisited. But until all of our components' constructors are refactored this isn't possible.
When that day comes we can remove this nasty compile-if, and the atom, and move to
a stateless startup sequence, where each component recieves the entire config map and
parses out the piece it's interested in.

(set! m)Set the config-map atom to configuration sourced from the envinronment,
probably from:
