Major changes to support cli-end-to-end demonstration. See full log

* notes/cli-end-to-end-demo.org (Database Aquisition):
  Starting description for the end-to-end demonstration workflow.
  Very simplified version of notes/cli-end-to-end.org

* docker-compose-demo.yml (services):
  Make the pre-populated ql database storage an explicit container
  to get persistent data and straightforward mount semantics.

* docker-compose-demo-build.yml (services):
  Add a docker-compose configuration for *building* the demo environment.

* demo/containers/dbsdata/Dockerfile:
  Add dbsdata Docker image to hold initialized minio database file tree

* client/containers/vscode/README.org
  Update vscode container to use custom plugin for later mrva redirection
