Remove product_category from metrics yml
Problem
When setting up a new metric the documentation suggests to add a product_category
from the categories.yml.
These categories, however do not map to very general metrics, such as hostname
, uuid
or [license_billable_users](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/config/metrics/license/20210531204603_license_billable_users.yml)
. Currently, these metrics use a product_category
called collection
, which is not part of categories.yml.
We discovered that product_category
is not really used right now anyway (see #393366 (comment 1295122962), #393366 (comment 1295377452)). Adding the product_category
is an effort every time a metric is created.
Desired Outcome
product_category
is removed from all metrics files and documentation.
