⬆️ Allow chunked public upload

[tessus]

State:

• Internal DAV endpoints support chunking (ChunkingV2Plugin)
• Public DAVv2 implemented allowing same logic as internal shares
• Frontend supports chunking
• DAV support for Chunking on public shares
  • Requires UploadHome to also support shares instead of only user sessions

Original issue:

I've noticed that for the file drop or any other screen that allows one to upload a file, there's no way to know in advance if the upload will fail.

Let's say the max upload size is 100 MB and someone tries to upload 105 MB. The upload will fail, but the person still uploaded 100MB for nothing. It would be nice, if there was a way to handle this scenario.
The easiest would be to show a message that tells an uploader the max upload size.

What do you think?

We plan to also do chunking on the web UI upload which would mean that we don't have a limit anymore.

Sadly I can't find the issue for this - @rullzer @jancborchardt @ChristophWurst Could you find it or was there none, yet?

Sounds good, but I suspect that implementing this chunking feature will take a while (months, years).

In the meantime a message would be great and very helpful. Adding the message won't be much of an effort for someone who knows the code.

Web UI does chunking since Nextcloud 13 - we ported exactly this pr in #7056. Don't know if files drop and unauthenticated is also supported as of now. cc @danxuliu

Any new update to this? Any chance this will come on next major release?
