1.  final class SequencedEventStoreBasedTopologyHeadInitializer extends SynchronizerTopologyClientHeadStateInitializer

   As not all events observable by the topology processor are topology transactions, updates the topology client's head based on either the sequenced event store or the topology store, depending on which one has a higher timestamp.

   As not all events observable by the topology processor are topology transactions, updates the topology client's head based on either the sequenced event store or the topology store, depending on which one has a higher timestamp. This becomes useful on restarts.

2.  final class SequencerSnapshotBasedTopologyHeadInitializer extends SynchronizerTopologyClientHeadStateInitializer

   For a provided sequencer snapshot, updates the topology client's head state up to sequencer.SequencerSnapshot.lastTs, because this is up to where the topology store is queried for the onboarding state.
