Add option to pt-table-checksum to override max execution

[monty solomon]

We configure our servers with a max execution time.

It would be useful to override that via an optimizer hint in the queries when running utilities like pt-table-checksum

[monty solomon (monty+launchpad)]

pt-table-checksum --no-check-binlog-format --function murmur_hash -h monty --recursion-method hosts --ignore-tables mysql.gtid_executed,mysql.engine_cost,mysql.server_cost --tables foo.bar

07-27T16:42:50 Skipping chunk 1 foo.bar because MySQL used only 4 bytes of the PRIMARY index instead of 13. See the --[no]check-plan documentation for more information.

pt-table-checksum --no-check-binlog-format --function murmur_hash -h monty --recursion-method hosts --ignore-tables mysql.gtid_executed,mysql.engine_cost,mysql.server_cost --tables foo.bar --no-check-plan

07-27T16:44:37 Error checksumming table foo.bar: DBD::mysql::st execute failed: Query execution was interrupted, maximum statement execution time exceeded
