Alessio Placitelli d353bf344f [fenix] Generate the activation ping and send it with Glean (https://github.com/mozilla-mobile/fenix/pull/1707)
This fetches the Google Advertising ID, salts it and
then applies hashing before sending a ping with it,
at startup. Hashing and salting are used in order
to prevent ourselves to correlate advertising IDs
from the same user running different products we
own off a single device. We will never send the
client_id and the Google Advertising ID in the same
ping.

# Telemetry
Fenix uses Mozilla's telemetry service (Glean) and LeanPlum to measure feature performance and engagement.
## Baseline ping
Fenix creates and tries to send a "baseline" ping when the app goes to the background. This baseline ping is defined by the [Glean](https://github.com/mozilla-mobile/android-components/blob/master/components/service/glean/docs/pings/pings.md) component and [documented in the Android Components repository](https://github.com/mozilla-mobile/android-components/blob/master/components/service/glean/docs/pings/baseline.md).
## Metrics ping
Fenix creates and tries to send a "baseline" ping. It is defined inside the [`metrics.yaml`](https://github.com/mozilla-mobile/fenix/blob/master/app/metrics.yaml) file. This ping includes things like wether or not Fenix is currently the default browser.
## Events
Fenix sends event pings that allows us to measure feature performance. These are defined inside the [`metrics.yaml`](https://github.com/mozilla-mobile/fenix/blob/master/app/metrics.yaml) file.
## Activation
Fenix sends an activation ping once, at startup. Further documentation can be found in the [`activation` ping](activation.md) docs.
## Leanplum Events
