We currently have a reference from the MongoDB.Driver.Tests project to the MongoDB.Driver.Core.Tests projects. The reason for the reference is to gain access to the RequiresServerAttribute.

But we shouldn't have a reference to the entire test project. That gives unintended access to everything in the project and can result in name conflicts or subtle bugs.

We should either just copy/adapt the one class that is currently being accessed via the reference, or create a helper DLL with the shared types that any test project can reference.
