I like the direction of this.

Where does verbosity affect control flow? That sounds strange.

And I don't think we should just *drop* `--verbose` parameters. I do
think it would be good to *have* them, either by promoting
previously-verbose output to `log::debug` and making the parameter
affect the filter, or by using a task-local variable we don't need to
hand down through all the function calls, though the latter might be a
bit more involved (given that eg. tokio's LocalKey is not inherited
across `spawn()`...)

As for the helper... I'm a bit unsure here.
We currently always pass "info", and we use "PBS_LOG" as env var
everywhere except the pxar binary.

While on the one hand flexibility would be nice... I think we could
also just drop the parameters (or make them `Option`s)?
