public abstract class ServerSidePartitionedMetrics

Not an ask from this customer, but should we update the cumulative metrics as well?

Updated to add a new ServerSideCumulativeMetrics member TotalRequestCharge. I'm also fine with just leaving this out. Adding this to ServerSideMetrics instead would make the abstraction less clean imo since we would have to add the request charge after the object has been created.

Edit: updated to add to ServerSideMetrics. This required adding an internal setter on the public ServerSideMetrics class which I am kinda iffy about. Can discuss offline if you have a preference on where the requestcharge should be located.

Follow up edit: Looks like this actually isn't allowed, from test: VerifyAllPublicClassesCanBeMocked : Assert.AreEqual failed. Expected:<0>. Actual:<1>. The following methods and properties should be virtual to allow mocking:Class:Microsoft.Azure.Cosmos.ServerSideMetrics; Member:set_RequestCharge.

Sorry for the confusion, reverting update and moving RequestCharge back to ServerSideCumulativeMetrics.
