We were asked to make some improvements to the PrimaryOnlyService infrastructure to help speed up development for the server-serverless team and other server engineers. There are a few important improvements we'd like to consider:

• Unify cancellation paths
• Improve the relationship between an instance's lifetime and its state document's lifetime.
• Improve how services check for conflicting instances before constructing a new instance.
• Fold 'checkIfOptionsConflict' into the base PrimaryOnlyService API.
• Use CancellableOperationContextFactory to create OperationContexts to remove the need for OpCtx tracking in the Client decoration

Before making a follow-up project to do this work, we will do a PoC to get an idea of what kind of work we need to do and what a good ideal end state would be that would take into account these various considerations
