Add new "docker-ensure-initdb.sh" script

This mimics the behavior of `docker-entrypoint.sh` before it starts the PostgreSQL server. It has three main goals/uses: 1. (most importantly) as an example of how to use "docker-entrypoint.sh" to extend/reuse the initialization behavior 2. ("docker-ensure-initdb.sh") as a Kubernetes "init container" to ensure the provided database directory is initialized; see also "startup probes" for an alternative solution (no-op if database is already initialized) 3. ("docker-enforce-initdb.sh") as part of CI to ensure the database is fully initialized before use (error if database is already initialized)
