[Telemetry] Sync Tabs

[vesta0]

Description & Product Manager / Data Scientist User Story

As a product manager, I want to understand how often our users access their synced tabs in the browser, so I can prioritize related features accordingly.

What questions will you answer with this data?

• How often (and what % of users) tap on a synced tab to open it in browser?

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.

Hi, I've just checked this matter on the latest Nightly 201216 using a Google Pixel 3a (Android 11) and it seems that the corresponding event type ping isn't generated.

@mcarare please review

Should be good to go, after the latest changes.
