* feat(seeding): seed accounts and pods with seeded-pod-config.json

* feat(seeding): dry up SeededPodInitializer by using RegistrationManager directly and make compatible with version/3.0.0

* feat(seeding): update seed config files to version 3.0.0 context

* feat(seeding): simplify seeded-root config by importing pre-existing prefilled-root config

* feat(seeding): Add seeding as a default initializer, update seeded pod copy and guide, change seeded pod config to array

* feat(seeding): remove template info from seeded pod guide, use mockFs, code style nit, fix redlock test
