feat(model-server)!: Use ENTRYPOINT instead of CMD in the provided Do…

…cker image

> You can use the exec form of ENTRYPOINT to set fairly stable default commands and arguments and then use either form of CMD to set additional defaults that are more likely to be changed.
See. https://docs.docker.com/engine/reference/builder/#exec-form-entrypoint-example

Using a ENTRYPOINT in model-server docker container makes passing arguments easier.
For example,
`docker run --rm -p 28101:28101 -it modelix/model-server ./run-model-server.sh -inmemory`
would be simplified to
`docker run --rm -p 28101:28101 -it modelix/model-server -inmemory`

This is a breaking change, because the previous ENTRYPOINT was the default `ENTRYPOINT ["/bin/sh", "-c"]`.
