Hi,

My change [1] to enable a consistent tracing mechanism for the many
scripts diskimage-builder runs during its build seems to have hit a
stalemate.

I hope we can agree that the current situation is not good.  When
trying to develop with diskimage-builder, I find myself constantly
going and fiddling with "set -x" in various scripts, requiring me
re-running things needlessly as I try and trace what's happening.
Conversley some scripts set -x all the time and give output when you
don't want it.

Now nodepool is using d-i-b more, it would be even nicer to have
consistency in the tracing so relevant info is captured in the image
build logs.

The crux of the issue seems to be some disagreement between reviewers
over having a single "trace everything" flag or a more fine-grained
approach, as currently implemented after it was asked for in reviews.

I must be honest, I feel a bit silly calling out essentially a
four-line patch here.  But it's been sitting around for months and
I've rebased it countless times.  Please diskimage-builder +2ers, can
we please decide on *something* and I'll implement it.
