Add Topology documentation

[manthanhd]

Topology project needs a wiki which can outline, in a reasonable level of detail examples on how to use topology as standalone as well as tests.

Also, it would be good to have some sort of server admin guide too.

Deliverables:

• [ ] Getting Started guide to Topology
• [ ] Server guide for running and hosting Topology server

The getting started guide will need to outline a simplest way to get topology up and running (maybe deploy Jenkins server using docker)?

Server guide will probably be a more detailed guide outlining how to run the topology server, storage instructions and caveats (if any).

For now we should just add links in the README to these two blog posts:

• Building RippleNet Topology
• Testing RippleNet
