Subject: [PATCH] Fix import log_handler error with publish_errors set

Sync from Olso.
Commit Id is Ibf28ba17f81b5ddeda653f6a3501ecac18ffcd42

This handler sends all error logs as rpc notifications.
Note: when using publish_errors you also need to set the
notification_driver option too.

Closes-bug: #1240349
Change-Id: Ie66b23af8da2e439e0ac2f5677f6a064e3dd3133
