Describe the enhancement:
Kernel exposes a metric for IO operations in progress with field 12 but the metricbeat diskio module doesn't exported it.
The [metric](https://github.com/shirou/gopsutil/blob/master/disk/disk_linu

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
