fix consumer, add a test consumer, more logging
the consumer was broken due to one of my trademark indentation
fails: the update function only got run for Autocloud messages
because it was indented into that block...
also add a test consumer (handy for, well, testing) which
listens for dev not prod messages and writes to files in /tmp.
Set up logging in the consumers, and do a bit more logging
throughout, especially some more debug logging.
