Nova should be able to clone servers

It should be possible to create a new server with some/all properties matching an existing server.

We have a use case: The stack is Charmed-kubernetes deployed on OpenStack deployed on MaaS. Kubernetes workers are deployed as servers in the OpenStack layer. When a kubernetes worker expansion is requested, several new servers must be created by nova. In many cases, those new servers are identical to existing servers, which are the older kubernetes workers. It would be useful to be able to create duplicate servers without having to manually provide necessary information, like image, flavor, and network.

$ openstack server clone <uuid-of-existing-server> name-of-new-server
