The main differences is that the new version of Raft is more strict about starting raft peers which already contain configurations. For a start, cluster will fail to start if the configured cluster peers are different from the Raft peers. The user will have to manually cleanup Raft (TODO: an ipfs-cluster-service command for it). Additionally, this commit adds extra options to the consensus/raft configuration section, adds tests and improves existing ones and improves certain code sections.
