Subject: Feat: Added a script to cleanup generic openstack objects
X-Git-Tag: v0.82.0^2
X-Git-Url: https://gerrit.linuxfoundation.org/infra/gitweb?a=commitdiff_plain;h=705b334b7333fcc0cb8e6847718d1223ddbe1564;p=releng%2Fglobal-jjb.git

Feat: Added a script to cleanup generic openstack objects

This script will by default replicate the cleanup ports script.
However, the standard behaviour can be overridden by providing
various variables that can change the objects being managed.
