I'll need to think about how to approximate this when we don't know ahead of time what level an SST will be ingested to.

Saw your comment in the issue, was thinking that would be enough.

Ack
To allow for async ingestion (being implemented) we don't reuse TableIngestInfo, and allow an approximate value for the bytes ingested into L0. These will be used in admission control to more precisely account for how much load an operation is adding to L0 (prototype is in https://github.com/cockroachdb/cockroach/blob/ec4149e310f9b383f87cc7ff8776258d72927394/pkg/util/admission/work_queue.go#L911). Fixes cockroachdb#1600
