Description

We have RawErasureEncoder and RawErasureDecoder interface separately, which simplifies the implementation of raw coders. This would require to configure raw encoder and decoder respectively for a ErasureCoder, which isn't convenient. To simplify the configuration, we would have coder factory to group encoder and decoder together so only a factory class needs to be configured.
