kernel <> datafusion expression conversion #3999
Description
Is your feature request related to a problem?
To properly leverage predicates for data skipping with delta kernel, we need to convert datafusion predicates to kernel ones.
To properly support arbitrary predicates, we need to also provide opaque expressions to cover expressions not within the kernel expression system.
Describe the solution you'd like
conversion functions between kernel and datafusion predicates.
