[rdo-list] [CI] tripleo-quickstart-extra's roles migrated from gerrithub to openstack

Greetings, TLDR version, tripleo-quickstart-roles have moved to the openstack upstream source control sytem. Details: All the additional git and gerrit repos used with tripleo-quickstart that have formally been housed in [1] gerrithub and github/redhat-openstack have been migrated to the upstream openstack git and gerrit [2]. Additional details regarding the move can be found here [3]. There are a few roles that were still being incubated in gerrithub that will be added one at a time via the review process. Additional details regarding the transition of tripleo-quickstart and tripleo-quickstart-extras to upstream can be found here [4] Thank you!
