Easy consumer

[mjallday]

balog consume <app_initialization options> -- options options

e.g. balog consume balanced_service.init -s /etc/balanced/balanced.conf -- -ldebug

right now if i want to integrate a consumer for the service i need to write a small script to scan the consumers and instantiate an engine and begin consumption of events.

what i'd like to be able to do is not write that runner but instead specify the init function that can be called, pass it some parameters and let balog write the runner for me.
