    Retrive non-tripleo containers from buildah images

    Due to fallback registry, non_tripleo_containers list does not
    contains the list of actual pulled containers, it needs to be
    retrived from buildah images output otherwise while pushing
    the containers it will fail complaining containers does not
    exists.

    In this patch, we are retriving the image id and then passing
    those image id to buildah to push it to content provider
    registry.

    It also collects only stdout from non_tripleo register
    ansible var to store necessary data in the file.
