1557358 - Consider dropping labeled booleans metric types in favor of a "label set" metric type

Status: RESOLVED DUPLICATE of bug 1557353

(Data Platform and Tools :: Glean: SDK, task, P3)

Description

[Georg Fritzsche [:gfritzsche]]

Labeled booleans allow recording multiple bools under different values, e.g. to record whether a specific subfeature of a feature set was used.

"For example you may want to find which URI schemes are used in your application, like "http", "https", "about""

Maybe we could instead use a more straight-forward data type here, like a "label set". It would behave as a set of unique string values (vs. a string list with non-uniques). E.g.:

val x: StringSetMetric
x.add("http")
x.add("http")
x.add("about")
// x now contains: {"http", "about"}
