    Make unused iscsi_num_targets, iser_num_targets configs as deprecated

    After introducing new iscsi target driver model via Change-Id:
    I43190d1dac33748fe55fa00f260f32ab209be656, configuration
    options of iscsi_num_targets and iser_num_targets are not
    used in these new scsi targets.

    This patch makes these unused configuration options as
    deprecated and adds warning messages to notify future removal
    of these configs to users.

    Also this patch removes _ensure_iscsi_targets() which uses these
    two config options from cxt scsi target because this method is
    never called anywhere.

    Closes-Bug: #1427904
    DocImpact: Two unused config options are deprecated
