ua-parser is not providing the device brand and model details

logstash ua-parser is not providing the device brand and model details. Below is the useragent string which i parsed in the python parser and can see its provided the device branch & model details which is very helpful for our reports.

"clientUserAgent": "MobileApp/1.3.19-Release (iPhone9,3; CPU iPhone OS 12_4 like Mac OS X)"

python ua-parser output:

"clientUserAgent": {
  "user_agent": {
    "major": null,
    "patch": null,
    "minor": null,
    "family": "Mobile Safari UI/WKWebView"
  },
  "device": {
    "brand": "Apple",
    "model": "iPhone9,3",
    "family": "iPhone"
  },
  "os": {
    "major": "12",
    "patch_minor": null,
    "patch": null,
    "minor": "4",
    "family": "iOS"
  },
  "string": "MobileApp/1.3.19-Release (iPhone9,3; CPU iPhone OS 12_4 like Mac OS X)"
}

But logstash ua-parser is missing the device branch and model details. Used the mutate filter and renamed the output.

logstash ua-parser output:

"clientUserAgent.device.family": "iPhone",
"clientUserAgent.os.family": "iOS",
"clientUserAgent.os.patch": "1",
"clientUserAgent.os.major": "12",
"clientUserAgent.os.minor": "4",
"clientUserAgent.user_agent.family": "Mobile Safari UI/WKWebView",
"clientUserAgent.string": "MobileApp/1.3.19-Release (iPhone9,3; CPU iPhone OS 12_4 like Mac OS X)"

Parser used in the filter has all the details of device (family, model and brand), but only family is keep and forced in the device entry... :(

I think it is not really hard to add these data in the file lib/logstash/filters/useragent.rb, around line 138.

@npipet @ChimbuChinnadurai I have prepared a version over here: https://github.com/fabiogermann/logstash-filter-useragent
But currently I have issues running the jruby tests
