Also add writer_native_spill_enabled session property.

@kewang1024 thanks for the change!

@kewang1024 LGTM. Can you check with @amitkdutta as we might need to update our internal job setup with the changed session properties. Thanks!

Will it work with old coordinator where native prefix is not passed? We can keep the worker backward compatible so that it can work with native and without native prefixed properties. Once coordinator is updated, we can remove anything that does not have native prefix.

I think it will work if old coordinator doesn't pass native prefix.

[amitkdutta]

Nice. Then lets just enhance the unit test to keep the legacy case. Once coordinator is updated, we can remove it.

[kewang1024]

Yes, it will work with old coordinator

@kewang1024 Lets keep the worker compatible with old coordinator.

Thanks @kewang1024 for adding the tests.
