Dav endpoint: add share note

[tobiasKaminsky]

In current file listing (http://localhost/nc/remote.php/webdav/$folder), we do not get the note of a share, which any user can set when creating a share.

So it would be nice, to have a new property to get this directly.
Otherwise all clients would have to do another call to server to get this info.

As discussed with @schiessle.

Maybe @rullzer @blizzz have a little spare time, to get this in for NC15 ❤️

GitMate.io thinks possibly related issues are #3801 (Adding appointment into shared calendar fails), #10218 (allow to add a personal note to a share), #10834 (Add support for room shares), #10255 (Add support for room shares), and #7242 (New shares should be added at the top of the list).

Can we get this into NC16? @rullzer @blizzz? ❤️

@tobiasKaminsky this is supposded to be read only, I guess?

[tobiasKaminsky]

Yes. For setting a note we already have an endpoint in share api.

I already tried to start yesterday evening. I can give you my branch.
