    Description

      Initial sync limits batches during oplog application to 5000 ops/dur::UncommittedBytesLimit (512 MB) while steady state replication has been limiting batches to 50,000 ops/100MB since commit b53a93270c8ea8ccc9f43a0cf0592353b0edd012 (SERVER-24242).

      Getting the batch limits from SyncTail will also allow us to tweak the maximum number of operations in each batch during initial sync using the server parameter replBatchLimitOperations.
