The Collation annotation mainly serves as a meta annotation that allows common access to retrieving collation values for annotated queries, aggregations, etc.
Original Pull Request: #4131
Introduce Aggregation.stage which allows to use a plain JSON String or any valid Bson representation to be used within an aggregation pipeline stage, without having to implement AggregationOperation directly.
The change allows to make use of driver native builder API for aggregates.

This commit introduces MergedJsonSchema and MergedJsonSchemaProperty that can be used to merge properties of multiple objects into one as long as the additions do not conflict with another (eg. due to usage of different types).
To resolve previously mentioned errors it is required to provide a ConflictResolutionFunction.

This commit introduce an option that allows users to opt in on using estimatedDocumentCount instead of countDocuments in case the used filter query is empty.
To still be able to retrieve the exact number of matching documents we also introduced MongoTemplate#exactCount.

This commit introduces support for creating a MongoJsonSchema containing encrypted fields for a given type based on mapping metadata.
Using the Encrypted annotation allows to derive required encryptMetadata and encrypt properties within a given (mapping)context.
@Document
@Encrypted(keyId = "...")
static class Patient {
// ...
@Encrypted(algorithm = "AEAD_AES_256_CBC_HMAC_SHA_512-Deterministic")
private Integer ssn;
}
MongoJsonSchemaCreator schemaCreator = MongoJsonSchemaCreator.create(mappingContext);
MongoJsonSchema patientSchema = schemaCreator
.filter(MongoJsonSchemaCreator.encryptedOnly())
.createSchemaFor(Patient.class);

This commit adds support for relational style One-To-Many references using a combination of ReadonlyProperty and @DocumentReference.
It allows to link types without explicitly storing the linking values within the document itself.
@Document
class Publisher {
@Id
ObjectId id;
// ...
@ReadOnlyProperty
@DocumentReference(lookup="{'publisherId':?#{#self._id} }")
List<Book> books;
}
