    Add unique names support for cont_exec_args method

    In I5617e11f5d315f408d818e1ce47aa68f4a0d777a we switched
    container_run_args to run the container cli run into a unique container
    name, but we forgot to do it for the container cli execs.

    So this patch will run the exec using the delegated container_name if we
    can otherwise fall back on the fixed container name.
