Feature/docker deployment

[ki-do]

packs current tmc into a docker image, also creates a tarball of the image. local file repos are just being copied into the image. for http repos, it first clones the repo and, then, saves it as a local file repository into the image, as well. for s3, currently nothing happens, as i'm not sure how to deal with them.

• Documentation is missing on the usage other than the help
• Running without the output tar argument causes a cool bug:

panic: runtime error: index out of range [1] with length 1

• in the above one, -r argument is ignored. All repos are packed
• I get creating docker image failed: failed to build Docker image: exit status 125 error
• These warnings/logs should be taken into account. Might be related to my docker version? It is Docker version 28.5.2, build ecc694264d:
