suite "subnet tracker":
Backfill support for ChainDAG (#3171) In the ChainDAG, 3 block pointers are kept: genesis, tail and head. This PR adds one more block pointer: the backfill block which represents the block that has been backfilled so far. When doing a checkpoint sync, a random block is given as starting point - this is the tail block, and we require that the tail block has a corresponding state. When backfilling, we end up with blocks without corresponding states, hence we cannot use `tail` as a backfill pointer - there is no state. Nonetheless, we need to keep track of where we are in the backfill process between restarts, such that we can answer GetBeaconBlocksByRange requests. This PR adds the basic support for backfill handling - it needs to be integrated with backfill sync, and the REST API needs to be adjusted to take advantage of the new backfilled blocks when responding to certain requests. Future work will also enable moving the tail in either direction: * pruning means moving the tail forward in time and removing states * backwards means recreating past states from genesis, such that intermediate states are recreated step by step all the way to the tail - at that point, tail, genesis and backfill will match up. * backfilling is done when backfill != genesis - later, this will be the WSS checkpoint instead
