filebeat

Greetings and thanks for this software.

I would like to request for adding the two processors uppercase and lowercase to filebeat input processing.

Besides being useful, adds to making things consistent.

Thanks for your time and attention

Feature idea, add beat info metrics from the stats endpoint /

{
  "beat": "pubsubbeat",
  "hostname": "pubsub-sidekiq-inf-gstg",
  "name": "pubsub-sidekiq-inf-gstg",
  "uuid": "FOO",
  "version": "7.5.1"
}

Would make a metrics like this:

pubsubbeat_build_info{version="7.5.1"} 1
pubsubbeat_beat_info{beat_name="pubsub-sidekiq-inf-gstg",uuid="FOO",} 1
