Add tripleo-ci-testing to tripleo-repos for use in periodics

For periodic containers build job tripleo-ci-testing makes more
sense than current. Used by [1] and tracked in [2]. The actual
tripleo-ci-testing repo is specified by [3] in rdo config.
You can see a test review in [4] which runs the periodic container
build job in check with this code.
