Similar to the parent task, we should modify the Envoy mesh configuration on wikikube to have a configurable sampling fraction to initiate traces. On debug pods we should default that to 1.0 (100%).

I mistakenly didn't annotate https://gerrit.wikimedia.org/r/c/operations/deployment-charts/+/994193 with this Bug and thus it isn't linked, but that patch has been the last in the series of patches to enable tracing in mwdebug pods in wikikube. I just also tested it once more it and appears to send traces quite fine, so resolving this.
