Task/Issue URL: https://app.asana.com/1/137249556945/project/72649045549333/task/1211382919613023?focus=true

Description

Remove default params from attributed metrics pixels.
Pixel renaming to use attributed_metric as prefix.
Add version as metric param (representing bucket version).
Includes sending origin, or install date as fallback.
Removes stored data outside monitoring window.

Steps to test this PR

This will be tested by privacy team to ensure:

• we don't include default params
• we strip form factor from pixel (no phone / tablet)
• we include origin or install date
• buckets include their version

Go to PrivacyFeatureName class and replace url by https://api.jsonblob.com/019a4fb1-89b3-7971-8c77-ab77969a5874
So it can be smoke tested optionally, to validate those parts.
