Ian Wienand b91207ae47 Remove _config_error thrower
"log and throw" is arguably an anti-pattern; the error message either
bubles-up into the exception, or the handler figures it out.  We have
an example where this logs, and then the handler in blockdevice.py
catches it and logs it again.

Less layers is better; just raise the exception, and use log.exception
to get tracebacks where handled.
