puppetboard/default_settings.py: Reverting PUPPETDB_HOST change from #187 (#260)

This change is only useful for Docker image building, but for officially
supported packages in PIP this change will cause unnecessary breakage to
existing users. We will have to implement a different approach for configuring
settings in Docker images.

Adding a note to README.rst indicating that an officially supported Docker
image is planned.
