Cluster is an interface representing a collection of members in one etcd cluster.
type Cluster interface {
// ID returns the cluster ID
ID() types.ID
// ClientURLs returns an aggregate set of all URLs on which this
// cluster is listening for client requests
ClientURLs() []string
// Members returns a slice of members sorted by their ID
Members() []*membership.Member
// Member retrieves a particular member based on ID, or nil if the
// member does not exist in the cluster
Member(id types.ID) *membership.Member
// Version is the cluster-wide minimum major.minor version.
Version() *semver.Version
