 Description   

Since reads on change collections are the way we will bill for change streams in serverless, we should add test coverage that reads on change collections generate RPU's.

It would also be nice to add test coverage that writes to change collections do not generate WPU's. Currently WPU's are blocked on change collections here.

We may want to update the test that was added for change streams reading from the oplog when RPUs/WPUs were first introduced.

janna.golden@mongodb.com : I'm adding this ticket to the PM-2968 project to make sure it doesn't fall through the cracks, and keep it assigned to me until someone from my team is available to take it on.

bernard.gorman@mongodb.com sebastien.mendez@mongodb.com Change Streams will be released in v7.2, so doing this in Q3 should be fine!

The Server Serverless team would like to request this ticket to be scheduled in Q2. Would be good to have for 7.1 so it can be scheduled towards the tail end of the quarter.
