Description

See DRILL-7480 for a discussion of the issues with how we currently use parameterized types in the metadata API.

This ticket is for short-term fixes that convert unsafe generic types of the form StatisticsHolder to the form StatisticsHolder<?> so that the compiler does not complain with many warnings (and a few Eclipse-only errors.)

The topic should be revisited later in the context of DRILL-7480.
