    Register targets to a target froup of an ALB. ``targets`` is either a
    instance id string or a list of instance id's.

    Returns:

    - ``True``: instance(s) registered successfully
    - ``False``: instance(s) failed to be registered

    CLI example:

    .. code-block:: bash

        salt myminion boto_elbv2.register_targets myelb instance_id
        salt myminion boto_elbv2.register_targets myelb "[instance_id,instance_id]"

            targetsdict.append({"Id": target})
    conn = _get_conn(region=region, key=key, keyid=keyid, profile=profile)
