We now allow to derive field names for a $project stage from a given type by including all top level fields.
// $project : { title : 1, author : 1 }

Use getCollectionName() in MongoTemplate.insert/save. Consistently use getCollectionName(Class) from ReactiveMongoTemplate and fluent API implementations.

Tested against 4.0.9 and 4.2.0-rc1 servers.
Added a delay and left a todo in one of the tests where the 4.2.0-rc1 server takes a bit longer than it predecessor when creating indexes which can lead to BackgroundOperationInProgressForNamespace errors.

Use the reworked version of the EntityCallback method lookup.
Also fix issues with callbacks not invoked when intended and rework the reactive flow by removing deeply nested constructs.
Update documentation and add EntityCallbacks to BulkOperations.
Original Pull Request: #742
We now use EntityCallback to invoke callback actions on entities before saving/before conversion to provide hooks that potentially modify an entity before persisting it.
We also provide a reactive variant of entity callbacks allowing to consume Reactor Context and to defer the actual activity.

Current MongoAnnotationProcessor still uses 3.x.x Querydsl package names.
Update package names to com.querydsl.core.annotations.* to use Querydsl annotations for code-generation.
Original pull request: #755.
We now support hashed index definitions via IndexOperations. Reading index information back allows to identify a hashed index via isHashed().
Original pull request: #750.
OutOperation now supports the expanded format for the $out aggregation operation if additional parameters, next to the target collection, are given.
Aggregation.out("out-col").insertDocuments().in("database-2").uniqueKey("field-1“);
{
$out : {
to : "out-col",
mode : "insertDocuments",
db : "database-2",
uniqueKey : "field-1"
}
}
We’ll stick to the 2.6 format if only a collection name has been set.
Aggregation.out("out-col“);
{ $out : "out-col" }
Original pull request: #740.
We now make sure to call the delegate AggregationOperationContext without potentially overriding arguments. Without this change potentially registered target types would be overridden with null.
We now apply propagate the cursor size to aggregation options. We introduced AggregationOptions.comment to propagate the meta comment to aggregation execution.
Original pull request: #743.
Use MongoQueryMethod.getDomainClass() instead of getRepositoryDomainType(). Simplify annotation presence indicator methods hasAnnotatedSort() and hasAnnotatedCollation(). Refactor getAnnotatedAggregation() to non-nullable method throwing IllegalStateException to be consistent with other getXxx() methods.
Simplify aggregation execution and consider collection/single element declaration for reactive execution.
Tweak docs.

Reuse collection name for index creation instead of resolving the collection for every index. Switch lambda to method reference.
Original pull request: #746.
We now lazily read the collection of an entity as it potentially requires a more expensive SpEL evaluation that might not have been required in fist place.
