Prune old blocks from peer

[denyeart]

Pruning old blocks from peer to alleviate concerns around long term storage growth.

The snapshot feature delivered in v2.3 enables organizations to compare ledgers on a channel and come to agreement around logical "checkpoints". These checkpointed snapshots can be saved off and used as a starting point for new peers so that they don't have to process all blocks since the genesis block. With the concept of snapshots and checkpoints established, it is feasible to prune blocks prior to the checkpointed ledger height.

This issue serves as a placeholder until a pruning RFC becomes available.

@jovandlt the next step is for somebody to prepare an RFC with the proposed pruning design. You are welcome to start an RFC, you can review the RFC process at https://github.com/hyperledger/fabric-rfcs/ and see the snapshot RFC to get some ideas of what a completed RFC looks like - https://github.com/hyperledger/fabric-rfcs/blob/main/text/0000-ledger-checkpointing.md.
