Nest DateHistogramCompositeAggregationSource does not have CalendarInterval and FixedInterval

[mehdimadani]

Interval is deprecated on version 7.2.0 and DateHistogramCompositeAggregationSource does not support FixedInterval and CalendarInterval.

These properties already implemented in DateHistogramAggregation but not in DateHistogramCompositeAggregationSource class.

Using Interval generates warning on each response.
