Reduce sleep time for finished bulkv2 jobs

[ddanielr]

Skips the sleep calculation when bulkv2 returns 1 or 0 as success cases.
Also removes an unnecessary max comparison as sleepTime will always be less than or equal to locationLess

I'm having a hard time understanding how these changes match the description:
Skips the sleep calculation when bulkv2 reports that it has waited for all tablet servers to respond. or Reduce sleep time for finished bulkv2 jobs

It seems like the only substantive change was the change from > 0 to (effectively) > 1, so it only skips computing a new sleepTime when it is exactly 1 (it was already skipped when it was 0). Does the value of 1 have special meaning? If so, I think there's a simpler to change to just change to > 1 and add a small comment explaining why we're skipping when it's that particular value.

@ddanielr, @keith-turner suggested an improvement to the log message. I see you marked that comment thread as resolved, but did not implement the suggested changes. I don't care one way or the other, but wanted to bring it to your attention before this is merged in case you overlooked it.

Yep I see that and have updated the comment message.
