# This function allows developers to specify the impacted scenario by adding
# the info about installer and scenario into the commit message or using
# the topic branch names. This results in either skipping the real verification
# totally or skipping the determining the installer and scenario programmatically.
# It is important to note that this feature is only available to generic scenarios
# and only single installer/scenario pair is allowed.

# before the signed-off and change-id lines.

# Pattern to be searched in Commit Message

# Examples:
#   deploy-scenario:os-odl-nofeature
#   installer-type:osa

#   deploy-scenario:k8-nosdn-nofeature
