Add endpoint selection logic to runTumblebug.sh

* Retrieve the external IP address
* Prompt the user to select endpoints
* Options:
  1) Use External IP for all components
  2) Use 'host.docker.internal' and 'localhost
      - Note - 'host.docker.internal' to communicate with Spider and Dragonfly containers
      - Note - 'localhost' for Tumblebug itself
