Disable enforced throttling for URL requests....

Disable enforced throttling for URL requests.

The throttling feature rejects outbound HTTP requests to a server for a period of time, when it finds that the server is returning 5XX.
This change disables the feature.

TEST=none
BUG=70412
Committed: http://src.chromium.org/viewvc/chrome?view=rev&revision=72214
