Christos Soulios d1637ca476 Backport: Refactor aggregation base classes to remove doEquals() and doHashCode() (#43363) ... This PR is a backport a of #43214 from v8.0.0 A number of the aggregation base classes have an abstract doEquals() and doHashCode() (e.g. InternalAggregation.java, AbstractPipelineAggregationBuilder.java). Theoretically this is so the sub-classes can add to the equals/hashCode and don't need to worry about calling super.equals(). In practice, it's mostly just confusing/inconsistent. And if there are more than two levels, we end up with situations like InternalMappedSignificantTerms which has to call super.doEquals() which defeats the point of having these overridable methods. This PR removes the do versions and just use equals/hashCode ensuring the super when necessary.		2019-06-19 22:31:06 +03:00
