 Description   

When MaxScale monitors ColumnStore nodes, it's possible that the node is able to process any DML for non-ColumnStore tables, but ColumnStore data are not available there (PMs failed, for example).

Monitors should check this, as it impacts the routing decisions.

See https://jira.mariadb.org/browse/MCOL-962 for the related request to get the information needed available via SQL.
