Adds JSON RPC API on web socket to dynamically configure bgp. This is
the initial support (there are still tons of APIs that are not
exported via JSON RPC API).
$ sudo PYTHONPATH=.:$PYTHONPATH ryu-manager
ryu/services/protocols/bgp/api/jsonrpc.py
ryu/services/protocols/bgp/application.py
then you can configure on another terminal:
~ fujita$ wsdump.py ws://127.0.0.1:8080/bgp/ws
Press Ctrl+C to quit
