Task management API reference

Hi, in the elastic{on} presentation on the 2.0 features a Task Management API was mentioned.
I don't find any further info about this. Is this a future feature, or where can I find some more information on this?

The slide (82)
on speakerdeck

Future feature, didn't make the cut for 2.0. There is a github ticket tracking it, which will be updated as things progress I imagine: https://github.com/elastic/elasticsearch/issues/6914

I am waiting on this feature, by when can we expect this feature?
