  - Merge "jjb: xci: bifrost-verify: Disable errexit when uploading logs"
  - jjb: xci: bifrost-verify: Disable errexit when uploading logs

    The errexit option is there to catch failures when the job is executed.
    We don't want to mark the entire job as failed when we have troubles
    uploading the logs when the actual job has passed so we disable the
    errexit option to make the whole process less aggressive. Moreover, we
    move the build log upload to the end of the operation so we can catch
    as much output as possible.
