basti/kn intervention

[strseb]

This Pr adds the most basic code needed to make sure we handle intels KN service.

For this i want to add a concept of "Interventions" as 3rdparty Software that interferes with us and therefore we intervene. Hopefully, this will be an empty folder.

For now let's add:
-> a detection for kn,
-> an API for the Extension to query detected interventions
-> Telemetry for kn, to make a rough case of how much we really should be focusing this on: should this just be a sumo article or do we really need to intervene.

A couple small nits, but looks good.

Holding off on approval until we have an r+ from a data steward. Let me know if you want me to get that process going - would be happy to pitch in on that.

Aren't these already included on lines 11 and 13?

truee, i have a new vscode addon that probably added that >:(

DATA REVIEW REQUEST

1. What questions will you answer with this data?

We're trying to measure how many users are having Intels "Killer Network" software installed.
It is a traffic prioritization engine pre-installed on some OEM's, and it breaks the VPN Split tunnel and the VPN Extension.

2. Why does Mozilla need to answer these questions? Are there benefits for users?

We want for a short period measure how many people are affected by this.
This will allow us to (them remove the probe) and formulate a solution.
A low impact count would just require a sumo article, a high impact count would make it valuable to notifiy the user about this breakage.

3. What alternative methods did you consider to answer these questions?
   Why were they not sufficient?

We did try to measure impact by observing web forums complaining about breakage, but the sample size is too small and skewed towards technical users.

4. Can current instrumentation answer these questions?

No.

5. List all proposed measurements and indicate the category of data collection for each
   measurement, using the Firefox data collection categories found on the Mozilla wiki.

Measurement Name	Measurement Description	Data Collection Category	Tracking Bug
sample.killer_network_detected	The Conflicting Service 'Killer network' is detected	technical	https://mozilla-hub.atlassian.net/browse/VPN-6606

6. Please provide a link to the documentation for this data collection which
   describes the ultimate data set in a public, complete, and accurate way.

This collection is Glean so is documented in the Glean Dictionary.

7. How long will this data be collected?

This collection has expiry '2025-06-30'.

8. What populations will you measure?

All channels, countries, and locales. No filters.

9. If this data collection is default on, what is the opt-out mechanism for users?

These collections are Glean. The opt-out can be found in the product's preferences.

10. Please provide a general description of how you will analyze this data.

We will use looker to check the results.

11. Where do you intend to share the results of your analysis?

They will be shared internally with the team.

12. Is there a third-party tool (i.e. not Glean or Telemetry) that you
    are proposing to use for this data collection?

No.
