This release introduces some breaking changes affecting configuration files and `go` integrations:
* Config: The old configuration format is no longer valid and cluster will fail to start from it. Configuration file needs to be re-initialized with `ipfs-cluster-service init`.
* Go: The `restapi` component has been renamed to `rest` and some of its public methods have been renamed.
* Go: Initializers (`New<Component>(...)`) for most components have changed to accept a `Config` object. Some initializers have been removed.
