Node
A node resource (Node) represents a node running Calico Cloud. When adding a host
to a Calico Cloud cluster, a node resource needs to be created which contains the
configuration for the cnx-node instance running on the host.
When starting a cnx-node instance, the name supplied to the instance should
match the name configured in the Node resource.
By default, starting a cnx-node instance will automatically create a node resource
using the hostname of the compute host.
This resource is not supported in kubectl.
