Review Comment:
Why List? Why not Set?

Review Comment:
There is already `HoodieIndexConfig#getDefaultIndexType` method which sets
default which gets called by the builder. That method sets value based on
execution engine. Why are we setting default here? I am not sure simple index
(which relies on spark lean join) would work with flink. cc @danny0405
