Catalog current state of timeseries metrics

What is it?

All metrics should be available for artifacts, projects, and collections. For example, commits_monthly applied to a project would be represented as commits_monthly_to_project.

We also plan to have variants for some metrics based on different "from" entity types (e.g., user groups). For example, commits_monthly_to_project_from_trusted_developers. See also #1997

We currently want to implement three types of time-series metrics:

Point-in-Time Metrics: These are single aggregate functions across the entire event history. Examples include first_commit_date, unique_contributor_count, and star_count.
Interval (Velocity) Metrics: These metrics analyze events over a discrete time interval. Examples include contributor_count_30_days and gas_fees_30_days.
Rate-of-Change (Acceleration) Metrics: These metrics analyze how an interval metric has increased or decreased over time. An example is net_change_in_contributor_count_30_days.

So far, we've only considered the first two types, though here is an example of the third type #837

The table below provides an update to #2004 in terms of metric requirements:
