[<= 1.9.1] Log Loss can occur when log group creation or retention policy API calls fail #314

In plugin versions 1.9.1 and earlier, this plugin incorrectly returned an unrecoverable failure for log group creation or log retention policy API failures. This will be fixed in 1.9.2+.

Because the chunk of records will not be retried, this leads to log loss.
