Refactorings in MongoTemplate [DATAMONGO-1169]

[spring-projects-issues]

Oliver Drotbohm opened DATAMONGO-1169 and commented

MongoTemplate has grown quite significantly over the last years. We should take a few steps to reduce its size a bit:

• move all nested classes into separate files
• extract logic to determine the collection name to be used into a dedicated component (EntityMetadata, could even include QueryMapper, too).
• move execution of aggregations into separate component
• use Query NULL-object to avoid repeated instantiation

We could also apply this refactoring to the related Query / DBobjectUtils: #257
