commit 73b133f94f1f352f2b4151ff4b0c7c1e58f88afd

A=>B=>A redirect for "no-cors" should result in "opaque" response type

This CL follows https://github.com/whatwg/fetch/pull/834. This CL
changes services/network only because I accidentally did the same thing
for blink::ResourceLoader, and what blink::ThreadableLoader does is
not important because blink::FetchManager has its own response type
setting logic.
