…fault (#7813) * Remove `COMBINE_BEFORE_INSERT` config being overridden for insert operations * Revisited Spark SQL feature configuration to allow dichotomy of having: - (Feature-)specific "default" configuration (that could be overridden by the user) - "Overriding" configuration (that could NOT be overridden by the user) * Restoring existing behavior for Insert Into to deduplicate by default (if pre-combine is specified) * Fixing compilation * Fixing compilation (one more time) * Fixing options combination ordering
