Give user the ability to disable the URL request throttler:

- Support the command line switch --disable-enforced-throttling. With this switch specified, the URL request throttler won't reject outgoing requests during the back-off peroid. Please note that in this case we still keep track of the back-off period, since we need it to determine retry intervals.
- Add a more detailed error page description for net::ERR_TEMPORARILY_THROTTLED.

BUG=66062
TEST=Without --disable-enforced-throttling switch:
  (1) Type in the addresss bar a URL which is expected to return 5XX.
  (2) Keep clicking the "reload" button.
  (3) After a few clicks, Chrome displays an error page explaining why a net::ERR_TEMPORARILY_THROTTLED error occurs.

With --disable-enforced-throttling switch:
  Following step (1) and (2) described above won't result in a net::ERR_TEMPORARILY_THROTTLED error page.
