Han Kang 4a680138c0 Fix double counting issue for request metrics on timeout. 
Currently we record request metrics during the normal request flow and
we also manually invoke `Record` in the timeout handler to record
timeouts. This means that we effectively double count whenever we
timeout. This PR renames the `Record` function to `RecordRequestError`
to more accurately reflect the intended side-effect of the function
call.
