Maintainer load threshold

A committer or maintainer becomes overloaded, and ineligible to add new ports or adopt orphaned ones, once all of the following are true:

• They maintain 100 or more ports,
• Their outdated ratio (per portscout/repology, calculated as in section 2b) is 10% or higher,
• That ratio has remained at or above 10% continuously for 30 days or more.
