Add cache-storage as a value of deliveryType in resource timing
This CL adds a new value |cache-storage| to the deliveryType field in
resource timing. It is specified when the response comes from
CacheStorage either via Fetch handler in the ServiceWorker or from
the static routing API when the cache rule is specified and used.
