The intent is to use the instance struct to hold the connection
to the database as well as metadata about the instance:
- version
- flavor (mariadb or mysql)
Change is similar to prometheus-community/postgres_exporter#785

The query introduced with #523 performs poorly when there
are sufficient numbers of columns in `information_schema.columns`.
* Added using the `table_schema` as a filter
* Added limit to the query

Add label aggregation for innodb_metrics buffer subsystem.
* Total can be ignored as it is an aggregation of data+misc+free
* Dirty pages are not aggregateable, keep as a separate metric.
For information_schema.innodb_metrics we can split out labels based on
the type of buffer page IO operation in the "buffer_page_io" subsystem.
* Simplify scrapeInnodbMetrics() by casting value to float64.
* Test for broken metric output from MySQL.
* Supress log messages in the test.
