this is part of the effort to make grenade summaries actually work in the gate like we expect, so that the base case can take the output out of the main console and into summary consoles for readability. Instead of duplicating the awk filter from devstack, create a new python tool for this, which lets us have much greater control and sanity in filtering out garbage that we don't care about.
