This is the smallest useful change to add structured logging. It adds
little useful logging, but builds a foundation for adding more useful
logging later, and for converging existing log messages to structured
one later.
Add some acceptance criteria for structured logging so that we do not
accidentally change the log messages we really, really care about.
Add dependencies on the slog and slog-json crates, which exist
precisely for structured logging.

Add a markdown document to document acceptance criteria for the CI
broker, and also how to verify they are being met. The document is
used by the Subplot software, and the verification is run as part of
"cargo test".
