Description
GL replaces dot with underscore in field names, before writing them to ES/OS.
Graylog2/graylog2-server#4583
Users are able to configure dot as a key separator in JSON Extractor. They are then surprised to find that field names end up with underscore instead.
We should prohibit use of dot as a key separator in the frontend to avoid this. Or stop substituting underscore.
