We do this in order to make it easier to analyze in GLAM: see the metric
descriptions for more details.
Additionally, we change the time unit to milliseconds to make it easier
to analyze in GLAM.
Earlier versions of Glean supported bug numbers of the metadata, but this causes
ambiguity, particularly for Fenix where issues exist in both Bugzilla and
Github. This just updates the Bugzilla numbers to full URLs.
We made the use of numbers an error sometime ago, but neglected to enforce this
on "pings" in addition to "metrics". A future version of `glean_parser` [1] will make
this an error and this will set Fenix up to be ready for that.

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.
