Remove ObjectSorage configuration in the configstore component

General Discussions
#1

According to the migration documentation, is it safe to remove the objectStorage part from the configstore component and its associated bucket?

    configstore:
      dataDir: /mnt/agola/local/configstore
      db:
        # example with a postgres db
        type: postgres
        connString: "postgres://@postgres-service/agola_configstore?sslmode=disable"
      objectStorage:
        type: s3
        # example with minio
        endpoint: "http://minio-service:9000"
        bucket: configstore
        accessKey: minio
        secretAccessKey: minio123
      web:
        listenAddress: ":4002"

If the response is yes, can you update the documentation or do you accept a PR about it?
