  - Merge "xci: Allow specifying scenario and installer in commit message"
  - xci: Allow specifying scenario and installer in commit message

    It is not always practical to try determining scenario and installer
    to run jobs programmatically. This change adds possibility to do that
    by parsing commit message and skipping the automatic scenario and
    installer extraction.
