feat(docker): /container-init.d for advanced initialization (#6577)
* Add initialization directory support to Docker image
* Add sharness test, fix bugs in init script
Fixed in init script:
- Added some missing quotes around expansions
- Fixed INIT_ARGS to not pass any args if IPFS_PROFILE isn't specified
- Use printf instead of "echo -e"
- Only run scripts in top-level of init dir
- Handle filenames correctly when finding init scripts (by using find + xargs)

* chore: docker cleanup
cleans up containers and images (useful when run on developer machine)

* remove container init documentation from README
There is already IPFS Docker documentation where this should live:
https://docs.ipfs.io/how-to/run-ipfs-inside-docker/
