[devel at bb.net] Tracking state of multiple latent workers

[Andrii Senkovych]

Hi Povilas,

Thanks for the info, I'll surely have a look on it. But it seems for
my case it will be sufficient to have a step that can query Data API
and put a list of workers into a Property for future use. Do you
perhaps know how to do this? I've used Buildbot in times of 0.8.x and
now struggling a bit with the new features.

Thank you.
