block: add 'speed' optional parameter to block-stream
Allow streaming operations to be started with an initial speed limit. This eliminates the window of time between starting streaming and issuing block-job-set-speed. Users should use the new optional 'speed' parameter instead so that speed limits are in effect immediately when the job starts.
