#684 adds header exchange service to rollkit nodes (sequencer, full, light), but currently it does not add syncer (part of header exchange service) to sequencer node, as it does not make sense in the single sequencer settings. Further, the design of the syncer in the multi-sequencer scenarios is not very clear and requires careful investigation which will be performed as part of this issue.
