Addurls and credentials

[mslw]

A question has been asked about handling of credentials in the context of datalad addurls.

A response was given, suggesting use of datalad (DataLad core), or uncurl (DataLad-next) special remote, and highlighting that in either case the urls need to be handled by a special remote with access to DataLad's credential system.

The original question included a suggestion of using username:password in URLs, which should be technically correct and should work. I was not sure why it didn't, but didn't investigate due to the alternatives seeming more natural.

For this issue, the question remains whether a KBI about the role of special remotes for URL handling is needed.
