Same as we did during the Buster migration.
The goal is to be able to compare profiling data with non-k8s deployment.

The config patch is live, but we're not yet getting any data:
dpifke@webperf1002:/srv/xenon/logs/hourly$ ls *k8s* ls: cannot access '*k8s*': No such file or directory
I see the subscribers active, along with the corresponding channels in Redis:
127.0.0.1:6379> pubsub channels 1) "excimer-k8s-wall" 2) "excimer-wall" 3) "excimer-k8s" 4) "excimer"
My guess is we're missing something in the mwdebug-k8s image; I'll investigate more tomorrow.

This is working now.
The sampling rate is the same as in production, so it's unlikely to produce much output for one-off requests via WikimediaDebug (which are probably better profiled via XHGui anyways), but will still produce useful data during benchmarking runs.
