The python-openvswitch package should build the json C extension

[Terry Wilson]

The C extension wrapping OVS's own json parser is 60x faster than the pure-python version currently being used. Profiling shows JSON parsing to be the biggest bottleneck using python-openvswitch IDL library.

setuptools can build the extension as long as the python-dev packages are installed and openvswitch-dev is installed. It should be available in OVS 2.6+

I've added the -dev BD's to the package with a recent upload; however the python native extension self depends on the package being built which I've not figured out yet; we probably need to expose some sort of libopenvswitch0{-dev} type package but I'm not sure.
