Merge pull request #3741 from krasi-georgiev/discovery-race

pasquier-s bde64cf5a6 Fix Kubernetes endpoints SD for empty subsets (#3660) 
* Fix Kubernetes endpoints SD for empty subsets

When an endpoints object has no associated pods (replica scaled to zero
for instance), the endpoints SD should return a target group with no
targets so that the SD manager propagates this information to the scrape
manager.

Fixes #3659

* Don't send nil target groups from the Kubernetes SD

This is to be consistent with the endpoints SD part.

Krasi Georgiev fe926e7829 update the discover tests 
the discovery test is now only testing update and get groups.
It doesn't do an e2e test but just a unit test of setting and receiving
target groups
