Refactor daser, pruner and syncer to allow for lower pruning window than sampling window

[zvolin]

We should allow lumina to sample beyond pruning window but drop data as we receive it. This allows ensuring data availability for last 30 days but contributing in reconstruction only for last day.
Ideally syncer and daser should be kept in sync, so that syncer doesn't introduce huge storage usage spikes by syncing headers faster than daser can sample them and drop data
