UPSTREAM: 49142: Slow-start batch pod creation of rs, rc, ds, jobs

[joelsmith]

xref kubernetes/kubernetes#49142
upstream issue: kubernetes/kubernetes#49145

This looks fairly invasive. Is it a regression from 3.6? Did it get picked into 1.7? Is there an issue or bug corresponding to the pick?

[joelsmith]

@deads2k sorry, I forgot to edit the PR comments with the xref to upstream. Also, I'm happy to have you review if you like, but @derekwaynecarr reviewed upstream so it might be easier to have him also review this pick PR. I'll go update the PR comment now with xref details.

My concern is more about impacts to being able to pick future maintenance into 3.7. Having a description of the problem is important to judging the tradeoff. Thanks for the links.

The upstream PR has merged and will be in 1.8. @derekwaynecarr is this ready for a review?

@joelddiaz - i would like the upstream fix to soak a few days before merging this.

[derekwaynecarr]

wrong joel, @joelsmith -- i want to let this soak for a few days upstream before merging.

[joelsmith]

Thanks, sounds good.

@derekwaynecarr kubernetes/kubernetes#49142 has been in upstream 10 days now. How long did we want this to soak?
