The default value for protocols.swift.urlPrefix is "swift", which makes
the Swift API available at http://host:port/swift/v1. However, in the
documentation our example says "/swift", which resulted in the
unexpected endpoint http://host:port//swift/v1.
Apparently, Ceph distinguishes between both values even though their
docs[1] seem to suggest that using leading slashes is fine.
This commit fixes the examples in the documentation to use the default
value "swift".
