Allow users to modify ArrowConfig when creating databricks connector

[Arpitpandey992]

Currently, it seems impossible to modify ArrowConfig, specifically UseArrowNativeDecimal because this configuration is not exposed to users. This causes DECIMAL column data to be always read as String instead of casting to arrowType.decimal128 or something equivalent.
Is there any workaround for setting this property while creating the connection?

I am also facing the same issue, databricks decimal type is getting converted to string which is affecting all of my downstream operations.
