[SPARK-8753][SQL] Create an IntervalType data type
We need a new data type to represent time intervals. Because we can't determine how many days in a month, so we need 2 values for interval: a int `months`, a long `microseconds`.
The interval literal syntax looks like:
`interval 3 years -4 month 4 weeks 3 second`
Because we use number of 100ns as value of `TimestampType`, so it may not makes sense to support nano second unit.
