Add additional sort orders for get_witnesses (missed_blocks, hbd_interest_rate)
Actually, missed_blocks is a pretty useless metric. We should change this to something like missed_block_in_last_week while we're at it. Required for block_explorer_ui#296 (closed)
Not sure how we're getting this info now, but seems like we should build a missed_blocks table that would be generally useful, beyond this one task. missed_blocks table would take the form of time_stamp, witness_id with timestamp the primary key. We could use this for example to show something that nothing I know of now can currently display (all the missed blocks over a time period) on a web page.
