[CARBONDATA-2823] Support streaming property with datamap
Since during query, carbondata get splits from streaming segment and
columnar segments repectively, we can support streaming with index
datamap.
For preaggregate datamap, it already supported streaming table, so here
we will remove the outdated comments.
