influxdb output: treat field type conflicts as a successful write
If we write a batch of points and get a "field type conflict" error message in return, we should drop the entire batch of points because this indicates that one or more points have a type that doesnt match the database. These errors will never go away on their own, and InfluxDB will successfully write the points that dont have a conflict. closes #2245
