Revise the Index code path with better abstraction

[hudi-bot]

we should add an interface {{SecondaryIndexKey}} and map it to allowable types? just to move the code to a nicer point.. i.e {{IntegerIndexKey}} {{FloatIndexkey}} etc..
interface SecondaryIndexKey { fromString() -> T toString(T) -> String }

 

Other context contribute to this

we should examine all existing index use case and factors and commonly seen procedures and make them unified under the same abstraction
