I think I generally messed these up on the original import as every
stat seems to refer to the same thing. Over time, the layout of
openstacksdk stats has changed meaning this doesn't work at all now.
Use stats that are actually in graphite which should show the overall
health of API requests.

grafyaml actually knows this is deprecated, but it's actually more
than that and doesn't work to refresh the variable at all now. "1"
means "on load" which is what we want.
