missing resetting timers in the http handlers

[nonsense]

We used to have http.request.$method.time resetting timers in every handler, but they seem to be gone.

We should add them back to the codebase, similar to:

	defer metrics.GetOrRegisterResettingTimer(fmt.Sprintf("peer.sendpriority_t.%d", priority), nil).UpdateSince(time.Now())
