Support query sizes more than 1B #1518
Description
We have several issues here:
- IPA rejects queries larger than 1B but there is no reason for that. Instead, we should reject queries that put more than 1B records on each individual shard
- Query size is not propagated correctly across shards. Right now, leader shard just broadcasts query size it received from report collector. This size is the size for the whole query and it is not indicative for query sizes that each shard will run
