Avoid using the Aggregation.DEFAULT_CONTEXT which does not map contained values to the according MongoDB representation. We now use a relaxed aggregation context, preserving given field names, where possible.
Original pull request: #890.
Avoid nullable method arguments and add assertions. Introduce build() method to AccumulatorFinalizeBuilder to build Accumulator without specifying a finalize function.

Rename AggregationPipeline.requiresRelaxedChecking() to containsUnionWith() to avoid the concept of field validation leaking into AggregationPipeline.
Refactor AggregationOperation to consistently check their type and fallback to the operator check to allow for consistent checks when using custo AggregationOperations.

We now support the $unionWith aggregation stage via the UnionWithOperation that performs a union of two collections by combining pipeline results, potentially containing duplicates, into a single result set that is handed over to the next stage.
In order to remove duplicates it is possible to append a GroupOperation right after UnionWithOperation.
If the UnionWithOperation uses a pipeline to process documents, field names within the pipeline will be treated as is. In order to map domain type property names to actual field names (considering potential org.springframework.data.mongodb.core.mapping.Field annotations) make sure the enclosing aggregation is a TypedAggregation and provide the target type for the $unionWith stage via mapFieldsTo(Class).

Simplify tests.
