Add a docker compose service for the csv consumer

[kordless]

The docker examples, docker-simple and docker-cluster both need a way to spin up a container, copy a CSV into it, then run the consumer, per the instructions:

idk/molecula-consumer-csv \
--auto-generate \
--index=allyourbase \
--files=sample.csv

Once the container starts, in that docker compose context, the container should have access to the docker naming scheme and docker network.

Implement a means to do this to the two repos and ensure it can consume the sample.csv file, which should be included in the example. All code should go under the respective example directories.
