MXS-1367: Retry interrupted queries

Browse Source 
The new `query_retries` parameter controls how many times an interrupted
query is retried. This retrying of interrupted queries will reduce the
rate of false positives that MaxScale monitors detect.

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