1767415 - Add telemetry for tcpByDefault Nimbus feature

Status: RESOLVED FIXED

(Core :: Privacy: Anti-Tracking, task, P1)

Description

[Paul Zühlcke [:pbz]]

We need a new scalar that keeps track of how many clients have the tcpByDefault Nimbus feature enabled.
Once we have a separate probe to keep track of the feature state, we can remove the code that sets the rollout scalar to 3 here: https://searchfox.org/mozilla-central/rev/ea1234192518e01694a88eac8ff090e4cadf5ca4/browser/components/BrowserGlue.jsm#1742
