SERVER-50349 Getting a writable collection now requires the caller to be inside a WUOW by default
There are three modes when accessing a writable Collection:
* Managed in WUOW (default)
* Unmanaged (users need to commit/rollback)
* Inplace that provides direct access to the Collection in the catalog. (Users need to ensure there's no concurrent operations going on)
Added a helper RAII type CollectionWriter that abstract the three modes above and also provides abstraction on different methods of accessing Collections (AutoGetCollection or manual lookups).
Writable Collection is aquired lazily when needed (usually inside a WUOW).
