Public bug reported:

To debug os-brick's attach and detach code developers and system
administrators rely on seeing  what commands are actually being executed
by os-brick.

The os-brick library relies on the DEBUG logs from the libraries (such
as ``oslo_concurrency.processutils``) for this purpose instead of
duplicating log entries by logging the calls and stdout-stderr itself.

The default configuration in Nova no longer logs those os-brick commands
when running on debug mode.

This issue was introduced when fixing bug #784062, as the fix was to set
ALL privsep calls to log only INFO level messages.

The current solution is to set the ``default_log_levels`` configuration
option in nova and include  ``oslo.privsep.daemon=DEBUG`` in it.

The default for os-brick should be the other way around, it should allow
emitting DEBUG messages on debug mode.
