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.
