Refactor configuration of ClusterLogForwarder

With this commit configuring the ClusterLogForwarder resource will be done with
a new parameter `openshift4_logging.clusterLogForwarder`, which will follow the
upstream convention / spec.

The old parameter `openshift4_logging.clusterLogForwarding` is deprecated, but
existing legacy config will be respected.
