HIP-1056 Use BlockHeader.first_transaction_consensus_time as consensusStart/consensusEnd

[xin-hedera]

Problem

In a block stream file, BlockHeader.first_transaction_consensus_time should be used to set BlockFile.consensusStart and optionally BlockFile.consensusEnd. This is especially important for block stream files without any event transactions, or the extreme case, without rounds at all.

The field used to be left as null due to consensus nodes bug, once we get a good sample block stream file, we should add the support.

Solution

• read BlockHeader.first_transaction_consensus_time, and set it to BlockFile.consensusStart and BlockFile.consensusEnd
