Setup a routine how to create indices initially

In order to create the indices programmatically we need to change the
default password for security concerns. To create the user we need to
start the neo4j database. So I decided to provide a bash script that
let us do it once the container are started.

In production we must change the NEO4J_PASSWORD.
