Is this necessary? Does snapshot + snapshot scanner cover the copy table side
and adding a snapshot mode to verifyReplication cover the need?

Anyone who're familiar with snapshot answer this question?
If snapshot scanner uses the same hdfs cluster, speed limit is needed too.

> Add option to limit the scan speed in CopyTable and VerifyReplication.
> When adding a new replication, we use 'CopyTable' to copy old data from
> online cluster to peer cluster. After that, we use 'VerifyReplication' to
> check the data consistency of two clusters.
> To reduce the impact the online cluster's service, we add an option to limit
> the scan speed.
