[Telemetry] Open in app banner

[vesta0]

Description & Product Manager / Data Scientist User Story

As a product manager, I want to know if the Open in App banner is an effective feature discoverability tool.

What questions will you answer with this data?

• How often users see the banner?
• How often users dismiss the banner?
• How often users tap on "go to settings" from the banner?

Acceptance Criteria

• ENG files a DS JIRA request outlining their methodology.
• DS sign off on instrumentation methodology addressing product questions.
• Event pings can be queried via re:dash
• Event pings can be queried via amplitude
• We are sending telemetry events for the actions listed in the requirements
• We have documented the telemetry
• We have asked a data steward to review the telemetry

Talked offline with Kate who confirmed with DS and Boek:

• The newly added metrics should log events, not counters anymore
• An an expiration date 6 months is preferred.
  Maybe if there is already related telemetry for that part of the screen / feature we can reuse the existing expiration date so that all related telemetry probes will be renewed at the same time.

Verified as fixed on the 2/1 Firefox Nightly build with Google Pixel (Android 10).
