how to set custom tag in filebeat output.elasticsearch _stream_fields about victoriametrics

[AndrewChubatiuk]

hey @dw130
it's possible to set custom fields in general options of filebeat (or for each input separately) and use them in elasticsearch output like this:

fields:
    region: xx1
    app: xx2
output.elasticsearch:
   hosts: ["http://localhost:9428/insert/elasticsearch/"]
   parameters:
      _msg_field: "message"
      _time_field: "@timestamp"
      _stream_fields: "host.hostname,log.file.path,fields.region,fields.app"
