VPP Python language binding - plugin support
- Moved Python generator tool to tools directory - Added build-vpp-api Makefile target - Generator now only creates a Python representation of the .api the rest of the framework is in the vpp_papi script - Each plugin has its own namespace. - Plugin Python files are installed in vpp_papi_plugins for easy use inside the build tree.
