What

Currently Marin3r only supports all namespaces. In RH-OAM we would like to limit this down to just the namespace we need to target. Marin3r can still support targeting all namespaces as a default, but ideally we would be allowed to specify just a single namespace for it to watch and operate against.

More details and discussion are happening in the https://github.com/3scale/marin3r/issues/58
