This is a separate issue to mirgate all necessary openstack slave templates & secrets from old jenkins https://codeready-workspaces-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/ to new containerized jenkins https://main-jenkins-csb-crwqe.cloud.paas.psi.redhat.com/

Reason for doing these in one issue (before all the jobs migration) is because changing the config/secrets requires jenkins master rebuild, which is easier, when there is not much workload on the jenkins yet.

DoD: 

• Gather what templates & secrets are being used
• Migrate those templates & secrets to new jenkins
• Do not migrate stuff, which is not being actively used.
