Add option "--name" to command "openstack object create"

Option "--name" can be used to set as the object name of
the file to be uploaded in the container. Similar to option
"--object-name" in command "swift upload". Added unit test case
to ensure an exception is raised when using option "--name" for
uploading multiple objects.
