(feat) enables globbing from http/s fsspec filesystem

[rudolfix]

Description

https filesystem over fsspec could not glob listings. this PR enables that:

• listing do not contain size and modified date - makes size optional and modified date to default to now(utc) (this fallback was present before)
• allows to get file details if one of the above is missing. this needs HEAD per file in listing so cost is significant

several tests got added
