Clojurians Log v2

If you want the fancy style of feature toggle, then you either need to: - re-read a config on every request which has http calls - just use functions which make a cached request to an external source - you could wrap this in aero so that in dev a constantly-style is returned, but it will depend on your use-case.

This is gonna be a nice bit of the arsenal for doing flippers on the backend.
