MILESTONE: Update high flow programming performance OpenFlow 1.3+ optimized path for extensions support

OPNFLWPLUG-791 is the following:
=======================================================================
Add a high performance end-to-end OpenFlow 1.3+ optimized flow programming path/pattern using OpenFlow Java 1.3 models directly. This will make it possible for future applications in Nitrogen which are specific to switches supporting OpenFlow 1.3 and above to achieve higher flow programming performance by getting rid of the translations from OpenFlow Plugin to OpenFlow Java models.
=======================================================================

Update the above approach for extensions support
