[FEATURE] Demo site

[justinanderson]

There should be a live, public example of ModelDB for people to play with. Visitors should get to browse both a Jupyter notebook with example models to run and ModelDB's Node.js frontend to see reports about those models.

Architecture:

• Single ModelDB server
  • Mongo server
  • ModelDB Java backend
  • ModelDB Node.js frontend
• Multiple ephemeral Jupyter notebooks with ModelDB python library
  • configurable-http-proxy to vend out notebooks
  • tmpnb to spawn new notebooks and cull idle and old ones

This will also require the creation of one or more .ipynb files that can be run by users to create reports in ModelDB.

Closed, and I updated the gh-pages site to include links to the demo sites.
