does sum function accept the new interval types?

sum operates over NumericType only, see

spark/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/aggregate/Sum.scala

Line 49 in 3a299aa

override def inputTypes: Seq[AbstractDataType] = Seq(NumericType)
. If you think we should support new intervals in it, let's do that separately since this PR is about operators +/-.
