PipelineDefinitionBuilderChangeStreamTInput, TIntermediate Method

Appends a $changeStream stage to the pipeline. Normally you would prefer to use the Watch method of IMongoCollectionTDocument. Only use this method if subsequent stages project away the resume token (the _id) or you don't want the resulting cursor to automatically resume.
