> Introduce the max attempts for Exponential Delay Restart Strategy

> Currently, Flink has 3 restart strategies, they are: fixed-delay,
> failure-rate and exponential-delay.
> The exponential-delay is suitable if a job continues to fail for a period of
> time. The fixed-delay and failure-rate has the max attempts mechanism, that
> means, the job won't restart and go to fail after the attempt exceeds the
> threshold of max attempts.
> The max attempts mechanism is reasonable, flink should not or need to
> infinitely restart the job if the job keeps failing. However, the
> exponential-delay doesn't have the max attempts mechanism.
> I propose introducing the
> `restart-strategy.exponential-delay.max-attempts-before-reset` to support the
> max attempts mechanism for exponential-delay. It means flink won't restart
> job if the number of job failures before reset exceeds
> max-attempts-before-reset when is exponential-delay is enabled.
