Code Issues Proposed changes

Remove os_ken/app and os_ken/services/protocols/bgp/api/jsonrpc modules 

The os_ken/services/protocols/bgp/api/jsonrpc.py module was using
os_ken/app and os_ken app is the only one which was using tinyrpc lib.
Modules under os_ken/app except os_ken/app/ofctl are not used in neutron
and neutron-dynamic-routing so lets drop them from the code.

With that we can also drop tinyrpc from the requirements file at all.

Topology Viewer
***************
os_ken.app.gui_topology.gui_topology provides topology visualization.
This depends on following os_ken applications.
======================== =================================================
os_ken.app.rest_topology Get node and link data.
os_ken.app.ws_topology Being notified change of link up/down.
os_ken.app.ofctl_rest Get flows of datapaths.
======================== =================================================
Usage
=====
Run mininet (or join your real environment)::
$ sudo mn --controller remote --topo tree,depth=3
Run GUI application::
$ PYTHONPATH=. ./bin/os_ken run --observe-links os_ken/app/gui_topology/gui_topology.py
Access http://<ip address of os_ken host>:8080 with your web browser.
