Components whose binaries do not depend on the PostgreSQL major
(pgBouncer, pgBadger, HAProxy, pgBackRest, Patroni), built once here and
pulled into every ppg:staging:<V> through obs/_aggregate files
(root/ppg/staging/_shared/<pkg>/obs/_aggregate → isv:percona:ppg:staging:common:tools). Mirrors PGDG's
rpm/redhat/main/common.
Also percona-pgadmin4 (pgAdmin 4), which no major aggregates: it is UBI 9
only and consumed by the ppg:staging:common:tools:containers image.
