Clients: add NoRename version of webdav

Motivation:

The Default WebDAV protocol impl supports renaming.  This allows
rsemanager to upload a file to a temporary and then rename the recently
uploaded file to the target.  Doing this is A Good Thing.

However, this approach doesn't work for object stores (at least, S3)
because they don't support server-side renaming.

Modification:

Following the approach adopted for gfal, this patch adds a NoRename
variant of webdav for use with presigned urls.

Result:

Rucio is now able to upload a file to an S3 endpoint using the webdav
protocol impl and the final problem described in rucio#7342 is resolved.
