We are still seeing memory issues on tpccbench/nodes=6/cpu=16/multi-az
which need to be investigated. Turn off background tracing while we do.

Touches #58298. We're also reverting an earlier commit as part of this
one (d2524007593289f6db5d997704c78045597d1789). This revert is needed given
we've not yet addressed an underlying bug (#59203).

Release note: None
