Unable to provide a suffix "-docker" to build container image registry

[Saravanan KR]

"openstack overcloud container image prepare" command is expecting the suffix to be provided with hypen like "-docker" to construct the image name like "openstack-nova-compute-docker". But argparse does not allow "-" (hypen) as start of option's value. So it is not possible to construct a image name with suffix.

Hypens can be internally added if a valid suffix is provided. Need to modify tripleo-common/container-images/overcloud_containers.yaml.j2 to handle this case.

    Add hypen to the prefix/suffix of container name if not provided

    If suffix is provided without hypen at the start, prefix hypen
    to the suffix, to support creation of image names like
    openstack-nova-compute-docker, where docker is the suffix.
    Also if prefix is provided without hypen at the end, add hypen
    at the end of the prefix.
