one of the problems we've got with tempest is the fact that config loading is tied into the class hierarchy. However there is no reason why it should be. If we instead create a config proxy object we can lazy load the actual config when we are executing, and not do it at import time. This could use future iteration, but it does a huge job in removing config from the object inheritance tree which massively simplifies our ability to use config variables throughout the code.
