Feature: Allow better control of the response flow chain from server filters

New filters allow control of the call chain by implementing new filter callbacks that allow returning a control value for stopping propagation. This allows for the better control of streamed data and response flow.

• Deprecate bool QgsFilter::onRequestReady(), bool QgsFilter::onSendResponse(), bool QgsFilter::onResponseComplete()
• Add new methods bool QgsFilter::onRequestReady(), bool QgsFilter::onSendResponse(), bool QgsFilter::onResponseComplete() which return boolean values for controlling data flow
• Handle flow control in QgsFilterResponseDecorator::flush()
