Provides means to cleanup after the call.
If the call has already finished normally (request stream has been completed and call result has been received), doesn't do anything.
Otherwise, requests cancellation of the call which should terminate all pending async operations associated with the call.
As a result, all resources being used by the call should be released eventually.
Remarks
Normally, there is no need for you to dispose the call unless you want to utilize the
"Cancel" semantics of invokingDispose.
