Description
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
Now that statistics are extended by @isidentical and others, we should be able to use statistics in Ballista as well.
This has some nice benefits for performance: https://github.com/apache/arrow-datafusion/pull/3889#issuecomment-1283276230
It looks like currently the statistics are disabled in Ballista (as DataFusion was hardcoded to use `collect_stat: false`.
**Describe the solution you'd like**
https://github.com/apache/arrow-datafusion/pull/3846
Use the new setting in DataFusion.

Research direction
Search the Ballista codebase for the hardcoded `collect_stat: false`, then compare the requested behavior with DataFusion PR #3846. Done means the table provider can use the new DataFusion setting so statistics are available to Ballista.
