Subject: [PATCH] Implement Guru meditation reports

Guru Meditation report can log runtime configuration of a given process,
along with thread status and greenthread status.
It greatly helps to check the process runtime status.

The usage is simple:
kill -SIGUSR2 {process-id}

With this we can show report of kuryr-kubernetes

Change-Id: I4cb2314bd25d3200781582b1e188139751666fd3
Implements: blueprint oslo-gmr
