For multitenant migrations with protocol "shard merge", when the recipient imports donor collections it may fail. The only retryable error we know of is if R's stable timestamp is < the D collections' checkpoint timestamp, aka startApplyingDonorOpTime. We can advance R's majority commit point as necessary (SERVER-61140) but the stable timestamp is updated a bit later than the majority commit point, so R needs a retry loop while it waits.
Question: if there's a WiredTiger error when R tries to import a D collection, how does R know the cause of the error? WT uses EINVAL to express many errors, not just "stable timestamp too old". If R can't determine the cause of the error, it won't know whether to retry.
