Gabe monitoring plugin

Create a monitoring namespace with a GenericFrame plugin that can frame in a given url, parameterized by hostname. This will allow arbitrary monitoring systems to be integrated into collins, for great justice. I was going to ideally have the url be parameterized like the callbacks are, with ```<tag>``` or ```<arbitrary_attribute>```, but couldnt wrap my head around the craziness that is the Decorator being used in the callback module.

I converted those methods to options, but the else None is still required in getContent, because we need to test if the asset is monitorable still. Update incoming
