pt-table-checksum Multi Tier Replication Support

Description

pt-table-checksum will emit a warning when connecting to a replica and its binlog_format is ROW, the tool will try to set it to STATEMENT - which does not make sense given the limitation of multi-tiered replication.

See report below:

 

 

Given this knowledge, we should simply convert the error like below into an meaningful warning.

For example:

There should be no need to attemp SET SESSION on the replica since it will be noop anyway.
