Slim image based on mambaorg/micromamba

[unkcpz]

This is an image similar to base but based on mambaorg/micromamba which is lightweight than jupyter/minimal-notebook without jupyter things pre-installed.
I think it is suitable as the basic "aiida only" image, has the advantages of:

1. The system user can be changed, and set as aiida as default.
2. Size is slim compared with base (741MB v.s 1.9 GB)
3. Easy to control the startup scripts.

I also give a docker-compose file and tested it in my workstation so that it can work well with the Postgre container and rabbitmq container in a composed stack.

• docker-compose image name configurable.
• Duplicate AiiDA config files with base image.
• Tests added

@unkcpz do you know why the base image is so large compared to the slim one? Is it all the Jupyter stuff? If not perhaps we could trim it down, but still be based on the jupyter/minimal-notebook?

[unkcpz]

We have the docker image for aiida-core, which are like the base and base-with-services from this repo.
We decided still keep using the jupyter notebook docker stack as the base image which relieves the burden to check the compatibility of jupyter components (e.g. jupyter-client, jupyter-server).

One more change we can have for this repo is we don't release the base and base-with-services to dockerhub and ghcr registry anymore. They only used internally for build lab and full-stack.
