> Split the S3A code into layers
> * S3AFileSystem
> * S3AStore + Impl
> * RawS3A + Impl
> S3AFS will create the others and start in order: DelegationTokens, RawS3A, S3AStore, Metastore
> this will involve wrapping all access of DTs, s3client, Metastore to block until that layer is complete, or raise an exception if instantiation of it/predecessor failed.
> New layers will all be subclasses of Service, split into Interface and Impl, so we can manage the init/start/stop lifecycle with existing code
