Situation

When we configure oauth for the sechub server, we need to set up a IDP server manually (run keycloak docker image manually and configure)

Wanted

A out-of-the box solution which can be used for integration test

Solution

• set up a docker and Dockerfile for keycloack
• add define and add custom realm to the start up
• implement a class (like LocalTestPostgreSQLStarter) to start and stop the container

we do not use https://github.com/dasniko/testcontainers-keycloak, to make the docker solution reusable in helm charts for a local setup.
