Description
What is changing?
The remaining CUD operations now subclass ModernizedOperation.
After implementing this PR, I noticed tests hanging in CI. I modified the leak checker to print which test in particular failed in order to debug the resource leak, and I left the improvements to the leak checker in this PR. The root cause of the leaks was errors thrown during command construction - a connection was never returned to the pool in this scenario.
Additionally, this PR uncovered a bug in the return type inference from executeOperation. Some operation subclasses override the return type of its superclass (ex: DeleteOneOperation returns a DeleteResult, but DeleteOperation returns Document). Before the changes to executeOperation in this PR, there are TS errors in collection.ts because TS infers that the return type of executeOperation is the superclass's return type, not the subclass's.
Is there new documentation needed for these changes?
What is the motivation for this change?
