Set up the logging module to print to stdout so we can capture info about processing in the console log. This patch changes the existing error and warning print messages, but logging will be more important when we integrate the reno for release notes printing later. Change-Id: Ibf94d8527b879b0075516b6bdb26b7f5f266b021 Signed-off-by: Doug Hellmann <doug@doughellmann.com>
