Elixir runtime-controlled supervision tree using feature flags (circuit breaker)

These snippets provide a foundation for starting and stopping supervision trees at runtime using feature flags (e.g. Launch Darkly).

Some things to note when adapting these snippets:

  1. application.ex needs to be adapted into an existing application. The important part is that each child spec provided is compliant, and that there is a feature flag (ld_key) specified.
  2. As written, if a feature flag fails for some reason, it defaults to starting all children. There is room for adaptation here as needed.
  3. This implementation will still require a FeatureFlags module to be available that implements is_on?/2. Adjust as needed to accomodate your own feature flag setup.
