    Make _ensure_default_security_group method atomic

    Method _ensure_default_security_group wasn't atomic as it first tries to get
    default SG and if that not exists in DB, it tries to create it.

    It may happend, like e.g. in Calico plugin that between
    get_default_sg_id method and create_security_group method, this default
    SG will be created by other neutron worker. And in such case there will
    be Duplicate entry exception raised.

    So this patch is adding handling of such exception.
