Egon Elbre 961e841bd7 all: fix error naming
errs.Class should not contain "error" in the name, since that causes a
lot of stutter in the error logs. As an example a log line could end up
looking like:

    ERROR node stats service error: satellitedbs error: node stats database error: no rows

Whereas something like:

    ERROR nodestats service: satellitedbs: nodestatsdb: no rows

Would contain all the necessary information without the stutter.
