Nik Everett e99f90fb46 Add more debugging information to rethrottles
I'm still trying to track down failures like:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+dockeralpine-periodic/1180/console

It looks like a task is hanging but I'm not sure why. So this
adds more logging for next time.
