Implement dandi:files extractor

[candleindark]

This PR implements the dandi:files extractor. Additionally, it reorganizes the Docker compose files and dot env template files so that port of services at host can be changed easily. This ease of change of service ports at host facilitate running different instances of DL-Registry in the same host, allowing experimentation of different setup within a host.

@yarikoptic This PR is ready for merge. Upon your decision on whether to make the extracted metadata by dandi:files available on the production instance of DL-Registry on Typhon, we can merge this PR with

datalad-registry/datalad_registry/conf.py

Line 56 in b6e9d5b

"dandi:files",

as is or commented.

@yarikoptic I think we should merge this one if you are OK with the implementation. If you are concerned with the performance impact, we can run the registry with the dandi:files metadata extractor disabled (the default, see last comment). Beside implementing the dandi:files metadata extractor, this PR reorganizes the Docker compose files and dot env template files so that port of services at host can be changed easily. I want those changes available in the master branch.

These is a live instance of DL-Registry with the changes in this PR and the dandi:files metadata extractor enabled on Typhon. You can experience the changes of this PR though that instance.
