Fixed ALF-10333: Publishing: Multiple publishing events are processed sequentially rather than in parallel

Publishing: Remove some operations from the Channel and ChannelType interface that really shouldn't be exposed. Also removed the PublishingQueue interface - the two operations it had are now on the PublishingService.
WQS: Removed obsolete references to publishing channels.
