Bring back "Load execution plan from the snapshot on the run when resume retrying""
Summary: This reverts commit bfb90e8b0b442f657e5256082d3116aefa8c330b. Added a subsetting case for the backfill logic that was previously failing - i'm ok keeping the from failure case a bit slower if it means a 'standard' backfill can do fewer gRPC calls
Test Plan: BK (new backfill test that phil added passes)
