This commit adds a new add option: "format". This option specifies how IPFS Cluster is expected to build the DAG when adding content. By default, it takes a "unixfs", which chunks and DAG-ifies as it did before, resulting in a UnixFSv1 DAG. Alternatively, it can be set to "car". In this case, Cluster will directly read blocks from the CAR file and add them. Adding CAR files or doing normal processing is independent from letting cluster do sharding or not. If sharding is ever enabled, Cluster could potentially shard a large CAR file among peers. Currently, importing CAR files is limited to a single CAR file with a single root (the one that is pinned). Future iterations may support multiple CARs and/or multiple roots by transparently wrapping them.
