queries on histogram statistics\r\n\r\nThis commit optimizes queries on native histograms when we only need\r\nto get the histogram count or sum value.\r\n\r\nThe approach uses an optimizer which can set a flag in the vector selector\r\nto hint to scanners that only histogram stats are needed for the query.\r\nWhen scanners detect this flag, they would use histogram decoders which return\r\nhistogram objects with populated values for sum, count and the counter reset hint,\r\ncompletely dropping buckets and spans.\r\n\r\nSigned-off-by: Filip Petkovski
