UI: Thingverse UI

[arunkpatra]

Thingverse UI
A UI is needed for Thingverse that exposes all operations with Thingverse Backend. All REST APIs exist already. Considering ReactJS as of now for the frontend app.

Proposed Solution

1. An intuitive UI which allows users to have a birds eye view of a running Thingverse instance.
2. Role based access allowing access to different functions/pages
3. Display information on registered things, connection status, metrics around inbound message rates, current state, history etc.
4. Show state of backend resources like cluster state, storage, network usage etc.
5. Allow fine grained control of Things.
