It's better to use a generic name for further use by other index

It's covered by the following checkState.

Review Comment:
hasInvertedIndexChange is not changed in loop, so should be check before loop

Review Comment:
modifyTableAddOrDropInvertedIndices is almost the same as
modifyTableAddOrDropColumns, can we try to merge them to reuse code as much as
possible.

Review Comment:
Adding indexDesc to thrift will add load for query rpc, can we limit it to
query with inverted index?
