* In Nightly and debug builds, the secret setting is shown
(via `FeatureFlags.fxSuggest`), and the feature is enabled by default
via the `fx-suggest.enabled` Nimbus variable.
* In Beta and Release, we still want to show the secret setting, but
disable the feature by default.
This commit adds the following measurements:
* A new value for the `fx_suggest.ping_type` metric,
`fxsuggest-impression`.
* An `fx_suggest.position` metric to capture the position of the
Firefox Suggest search suggestion in the awesomebar, for impressions
and clicks.
* An `fx_suggest.is_clicked` metric, to capture whether an
`fxsuggest-impression` ping is for a clicked suggestion.
This commit also:
* Mounts `FxSuggestFactsMiddleware` to collect facts for impressions
and clicks.
* Dispatches `AwesomeBarAction`s from the `SearchDialogController` in
response to user interactions with the awesomebar and toolbar.
This commit builds on bug 1857092 to record impressions for sponsored
Firefox Suggest search suggestions, and moves the logic for recording
clicks to the same middleware.
An impression means, "did the user see a suggestion when they finished
engaging with the awesomebar?" A "finished engagement" means the user
navigated to a URL, a search results page, or a shown suggestion.
We don't record impressions for:
* Suggestions that the user sees as they're typing.
* Abandoned engagements, when the user dismisses the awesomebar without
navigating to a destination.
If the user taps on a Firefox Suggest suggestion, we record an
impression _and_ a click for that suggestion. If they tap on any other
suggestion, or navigate to a URL or search results page, we record an
impression only.
The new `FxSuggestFactsMiddleware` in this commit observes the
`EngagementFinished` action added in the last commit, and emits facts
for impressions and clicks.
