The final commit is the relevant one, description copied below. The other two commits are cleanups on the way there.
Our ability to debug #1613 was hampered by the control-plane-agent
ringbuf being overwritten, on average, every 1.5 seconds. This adds a
secondary ringbuf that only holds "important" events -- specifically,
commands received from the network that affect the host.
Unfortunately due to the BSP structure in the agent right now, this
required copy-pasting a change into three files. Fixing that appears
difficult.
