Description
The DeltaScanBuilder used by DeltaTable's TableProvider impl does not specify DeltaScanConfig. The builder uses Default for DeltaScanConfig and thus enable_parquet_pushdown is disabled.
This change makes it so DeltaScanConfig is an Option on the scan builder. If unset during build a default value will be created using the DeltaScanConfigBuilder rather than DeltaScanConfig::Default. The former has enable_parquet_pushdown defaulted to true. I considered changing the latter but it is used in a couple other places where I was not sure of the impact.
