Markus Mäkelä 9280f1a5d7 MXS-1367: Add timeouts for retried queries 
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.

Changed Features

Internal Query Retries

The internal SQL queries that MaxScale executes to load database users as well as monitor the database itself can now be automatically retried if they are interrupted. The new global parameter, query_retries controls the number of retry attempts each query will receive if it fails due to a network problem. The query_retry_timeout global parameter controls the total timeout for the retries.

To enable this functionality, add query_retries=<number-of-retries> under the [maxscale] section where is a positive integer.
