> When startup LogManager, we'll create schedule tasks like: 
> kafka-log-retention, kafka-recovery-point-checkpoint threads...etc 
> ([here|https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/log/LogManager.scala#L629]).
>  All of them have public configs to configure the interval, like 
> `log.retention.check.interval.ms`. But in addition to the scheduler interval, 
> there's a hard coded InitialTaskDelayMs (30 seconds) for all of them. That 
> might not be a problem in production env, since it'll make the kafka server 
> start up faster. But in test env, the 30 secs delay means if there are tests 
> verifying the behaviors like log retention, it'll take 30 secs up to complete 
> the tests.
> To speed up tests, we should create an internal config (ex: 
> "log.initial.task.delay.ms") to control InitialTaskDelayMs in LogManager to 
> speed up tests. This is not intended to be used by normal users, just for 
> speeding up testing usage.
