Doc fields added by Filebeat aren't included in index pattern field list

[Bargs]

Things like beat.name, type, offset. They're sent by Filebeat by default so they show up in Discover's doc viewer with a warning icon about how they're not in Kibana's mapping cache. I'm not sure how we fix it in the short term since it would require Kibana to have special knowledge about which fields Filebeat exports by default. Even then, the user has the ability to configure which fields are included, so the defaults might not be right.

I'm thinking we should just live with it the way it is for now. Long term we'll be getting rid of the field cache (#6498) which will make this problem disappear entirely. I'd like to know if other people agree with this conclusion.

You can always manually refresh mappings in the index pattern tool in the Management app.
