The total timeout for the retrying of interrupted queries can now be configured with the `query_retry_timeout` parameter. It controls the total timeout in seconds that the query can take. The actual connection, read and write timeouts of the connector aren't a good configuration value to use for abstracted queries as the time that it takes to execute a query can be composed of both connections, reads and writes. This is caused by the usage of MYSQL_OPT_RECONNECT that hides the fact that the connector reconnects to the server when a query is attempted.
