When AddPoint is called with the unknown metric type, it tries to infer the type from the given field names. Right now it infers histogram when any of the fields matches the histogram keys, but that leads to a lot of errors when your data isn't actually a histogram. Instead, only infer a histogram if all fields match the expected histogram keys.
Fixes #312
and maybe also influxdata/telegraf#14371 ?
