Use the StreamKeyValueParser helper to parse stream configuration from the command line. This extends qcam to accept role hints and pixel format in addition to a size. Currently only one viewfinder stream is supported, add a check to keep this behavior. Going forward this restriction will be lifted to support more then one stream.
