Beat exporter need support `filebeat.inputs - type: log`; but not the deprecated `filebeat.prospectors: - input_type: log`

Line 30 in 67af338

} `json:"prospector"`

Basically, just need replace "prospector" with "input" at the above line.

Please note that filebeat.prospectors is now deprecated and people should start using filebeat.inputs in their filebeat.yml instead.

Deprecated:

filebeat.prospectors:
- input_type: log

New:

filebeat.inputs:
- type: log
  paths:
  - /var/log/*.log
  - /var/log/*/*.log
  - /var/log/*/*/*.log
  - /var/log/*/*/*/*.log

Here is what curl http://localhost:5066/stats will show for filebeat.input from FB 6.4.1

  "filebeat": {
    "events": {
      "active": 11,
      "added": 497,
      "done": 486
    },
    "harvester": {
      "closed": 0,
      "open_files": 6,
      "running": 6,
      "skipped": 0,
      "started": 6
    },
    "input": {
      "log": {
        "files": {
          "renamed": 0,
          "truncated": 0
        }
      }
    }
  }

@duhang thanks, i'll check it out, maybe you could grab whole json output of /stats endpoint and attach it to this issue?

Here you go!
