fix(outputs.parquet): Reserve the timestamp column for the metric time

[81reap]

Telegraf reserves an int64 timestamp_field_name column for the metric time, but gets conflicting names would carry the same name and two different types. A bad input would go to the int64 builder and panic. (eg :: demo timestamp="x")

Now telegraf drops fields or tags that collide with reserved column names and log the exception.
