Subject: xci: Improve scenario bootstrapping process
X-Git-Tag: 6.0.0~17
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=36992029ed404569304187779492a4d737d6fc50;p=releng-xci.git
xci: Improve scenario bootstrapping process
It's best to check whether the scenario/distro/flavor combination is
supported before spending time cloning all the scenarios. Moreover,
we can record the scenario information as a local fact so we can use
it during the deployment later on.
