feat: Add support for hosting an artifacthub-repo.yml file

[cbuto]

Fixes #419.

This is an initial take at hosting an artifacthub-repo.yml from ChartMuseum.

Currently, it will only support setting the repositoryID in the artifacthub-repo.yml file, but adding more fields in the future shouldn't be too difficult.

Let me know what you think, especially the CLI flag implementation for multitenancy.

For me , I can accept the flag set mechanism for multi-tenancy but it maybe hard to set those flags if users have a large set of tenancy , any thoughts about the stdin (i.e.: json file stdin) ?

yeah it definitely could be cumbersome to set all the flags. Reading a json file could work but that feels cumbersome for cases where users only use depth=0 or a small number of repos 🤔. Maybe supporting a combination of the two could be implemented in the future once we get some feedback?

Yeah , I mean that .
