This script will scan an autotest server results directory for job result
directories that have completed and that have not yet been published on
a remote dashboard server matching given filtering options and for those it
finds it will rsync them to the tko server and mark them as published (it uses
a <jobdir>/.tko_published flag file to determine if a jobdir results directory
has been published yet).
