Nivy updated CASSANDRA-21102:
-----------------------------
Description:
The upper bound for repair retry backoff is multiplied by 2^attempts, but
attempts always starts at 1. This means we always wait (at maximum) twice as
long for the first retry attempt.
Rather than modify the complex regex string defining retries, we can modify
LatencyModifier to interpret this exponent as max(0, attempts - 1).
