24e96ee: signRequest can now return the object key it signed for, as key next to url. When a signing server stores the object under a different key than the one Uppy proposed (a directory prefix, a server-generated name), returning { url, key } from the request that creates the upload, the single-part PUT, or the multipart create, makes Uppy use that key for the rest of the upload and report it in upload-success. Previously the client-generated key was reported even when the server had stored the object elsewhere (#6496).
key is optional. Signers that return only { url } are unchanged. Requests that carry an uploadId must be signed for the key they receive; a key returned on those requests is ignored.
