I would suggest keeping line 215 and removing the randomization logic here. Have
the DRP-related caller do the randomization and pass it into |retry_delay|.

Done.

     // Randomize the timeout over a range from one to five minutes.
     retry_delay =
         TimeDelta::FromMilliseconds(
             base::RandInt(1 * 60 * 1000, 5 * 60 * 1000));
-#else
-    retry_delay = TimeDelta::FromMinutes(5);
-#endif
