tripleo-ci centos-7 based jobs running on stable/train needs to adjusted.
* All centos-7 based standalone scenario jobs
* Undercloud jobs

These projects have jobs coming from template:
* tripleo-puppet-elements
* tripleo-image-elements
* os-refresh-config
* os-net-config
* os-apply-config
* os-apply-config

Move these jobs to c8

## Missing centos-8 train jobs

* tripleo-heat-template - Bhagyashri
* jobs:
* tripleo-ci-centos-7-standalone-upgrade-stein -
* Do we have same job for c8 something like c8-standalone-upgrade?
* As c7 staein to c8 train upgrade is not available yet so should we keep this job or should we remove this?
* tripleo-ci-centos-7-scenario010-multinode-oooq-container-
* Missing c8 version of this job
* fs038
* NOTE: we can remove this job, as fs038 is used in stein & queens, is replaced with standalone sc10 for octavia testing.
* tripleo-ci-centos-7-scenario011-multinode-oooq-container-
* Missing c8 version of this job
* fs044
* https://opendev.org/openstack/tripleo-ci/src/branch/master/zuul.d/multinode-jobs.yaml#L529 weired
* https://opendev.org/openstack/tripleo-quickstart/src/branch/master/config/general_config there is no fs044
* It can also be removed
* tripleo-ci-centos-7-scenario006-multinode-oooq-container -
* Missing c8 version of this job
* fs026
* IT is a validation specific job: https://opendev.org/openstack/tripleo-quickstart/src/branch/master/config/general_config/featureset006.yml
* I think we can repurpose this job for validation testing
* Action items: Check with Tengu & wes on irc how to repurpose this fs
* currently we can remove this job but add a bug or taiga card for repurpose

* tripleo-ansible - Pooja
* jobs:
* tripleo-ci-centos-7-standalone-upgrade-train -
* Missing c8 version of this job
