Consider whether OperationInternalBase.ApplyStateAsync should throw

[heaths]

As discussed, we should consider whether ApplyStateAsync should throw, given that our existing LRO contract was that UpdateStatus and UpdateStatusAsync should not throw; however, if LROs have no Value property, where else would we throw?

@heaths if I am not mistaken this is not specific to KV and is a behavior change question on the shared code?

Looking through the code, this seems no longer relevant since KV is using the operation helpers and other common infrastructure.
