Pass SessionState to TableProvider #2658

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

Describe the solution you'd like
I would like to expose a &SessionState to TableProvider::scan to allow them to make use of session state for query planning
Describe alternatives you've considered
