feat: shorten docker command arguments by leveraging CMD

[kunish]

As the title suggests, this PR is to shorten docker command user arguments by adding default ENTRYPOINT and
CMD to Dockerfile, which is used in the CI/CD build steps.

Before

docker exec dae dae reload

After

docker exec dae reload

Thanks for your PR!

dae does not listen on port 2023 like dae-wing, thus we have no need to expose it.

And why we need an independent CMD [ ] ?

[kunish]

See this article, which explains in detail the main differences and usecases between these two Dockerfile commands.

In short

Use CMD to specify the default command to be executed when running a container from the image.

Use ENTRYPOINT to specify the main command to execute when the container starts.

My mistake. I was confused with another project we are working on.

@kunish Thank you for your explanation. I think it has been ready to merge.

Just a quick reminder, we need to also change the instructions on dockerhub README

@kunish I'll do it later. Thanks.
