Replace calls to old repo-updater store and types by the new store
Created by: asdine
This PR removes the repo-updater Store
type and replaces all calls to that store by the new one.
Services outside of repo-updater now use the internal/db
stores instead of relying on repo-updater.
All repo-updater Repo and ExternalService types have been removed, and their logic transfered to types.Repo
and types.ExternalService
.
