hive-test-kube not running tests

[Zoltan Haindrich <ki...@rxd.hu>]

Hey All!

I guess some of you have noticed that sometimes builds doesn't start.
This was caused by that I've undersized the volume supposed to hold the build artifacts when I've originally created it...so the build results have filled up the disk...and 
it was not able to record results anymore...

I wanted to fix this by enabling branch indexing, because that will also remove old builds as well (so I just removed some garbage when I first saw this) but that would 
cause a bit of a trouble for us right now; so I should left it disabled.

I've resized the volume to provide adequate space for at least a few months.

Without branch indexing it will not notice which PRs were missed...will get to that soon; I've already prototyped the solution but deploying it will rerun tests on all open 
PRs..

cheers,
Zoltan
