Share jail: how to rename shares?

[kulmann]

Describe the bug

Before the share jail, renaming a share is a MOVE on the mountpoint in the personal home via webdav v2 personal home.
After the share jail, renaming a share would be a MOVE on a webdav root, i.e. dav/spaces/<share jail id>!<share id>. Which is kind of expected. But this brings up the question of how to rename a share per user. Is that forbidden in oCIS for now? Does it need an entirely new concept?

We've disabled renaming shares in the web ui for now when the share jail is enabled via capabilities. So this is not urgent, but still a regression.

cs3org/reva#2884 got merged. It should be possible to do a rename in the share jail.

https://github.com/cs3org/reva/blob/80f88dfbc02d9a6ab6ecf94543927286fdcd0fd2/internal/grpc/services/sharesstorageprovider/sharesstorageprovider.go#L600 does seem to implement it, but it needs to be tested manually.

I think we can drop the needs concept tag

[butonic]

stat and move requests need to handle more cases to make this possible. work is started with cs3org/reva#2886 but I'll go play with the parallel deployment now ...

[butonic]

should be fixed with cs3org/reva#2904, cs3org/reva#2886 was only a partial fix

With https://github.com/owncloud/ocis/releases/tag/v2.0.0-beta.3 the share jail can be used to rename a share mount point by sending a MOVE /dav/spaces/{sharejailid}/oldname with a Destination: .../dav/spaces/{sharejailid}/newname.
