In
missing_blocks_auditor
, add an estimate of the gap size when there's a missing block.The gap estimate is the height of the unparented block, minus the maximum block height less than that height, minus 1.
It's an estimate, because we don't know there's a chain between the unparented block and that block of maximum height.
