class delete :?strip_prefix:string -> string ->delete_call_t
new delete uri: Deletes the document or collection at uri.
Deletions are always recursive (the whole tree is deleted).
On success, the expected status value is `No_content. When some URLs
of the tree to delete result in errors, the status value will
be `Multi_status reporting the errors. In that case the delete
was only incompletely performed.
