1. Add a demo script that runs with a single curl command to install osprey, start services and the example event generator. It will check for existing docker services and port collisions. This overlaps a bit with start.sh. Command:

curl -sSL https://raw.githubusercontent.com/roostorg/osprey/main/demo.sh | bash

2. Removed bigtable
3. Fix a bug in kafka rename
