Add an opt-out header for HTTP throttling. Never throttle for localhost.
Added net::IsLocalhost() function to net/base/net_utils.h
Unit tests for the above. Also fix flakiness in the ReceivedContentMalformed test that was caused by non-zero jitter.
Modify back-off policy to ignore first 4 errors to help avoid back-off from erroneously kicking in on flaky connections. Make maximum back-off period 15 minutes instead of 60. Added documentation of results of analyzing behavior this new policy will give.
Add a simple server for manual testing of the throttling feature.
