Lock on session start level with provided keys

Scenario: Parallel DB updates with transactions on multiple collections that use same documents. Example: Calculate some common stuff to embed it in extra collections to avoid lookups. Problem: Lock and timeout on documents uses up valuable time and performance. Also lock conflicts produce a huge amount of exceptions that need to be handled. Idea: Key-based sessions Example: Session A with Keys 1 and 2 is started. Session B tries to start with Key 1. Key 1 is locked with Session A. Session B waits till Session A is finished. In this case transaction doesn't start with updating and failing. Waiting for session doesn't use up resources.
