refactor(ansible): Estandariza nombres de roles y actualiza Koji

Se estandarizan los nombres de los directorios de roles, cambiando guiones por guiones bajos.

Se añaden nuevos scripts para limpieza y callbacks en Koji Hub. Además, se actualizan las configuraciones de Kojid, Kojira y PostgreSQL, incluyendo la instalación de paquetes, ajustes de mock y la gestión de variables.
