Can't add qemu options when launch an instance

[caozhengyx]

What are you trying to do?

The vm launched by multipass does not have the file /sys/class/dmi/id/product_uuid. I want add -uuid $(uuidgen) to "qemu-system-x86_64".

What's your proposed solution?

Add a option to launch sub command, for example:

$ multipass launch -uuid xxx

Additional context

The kubernetes official website documentation says "Kubernetes uses these values to uniquely identify the nodes in the cluster. If these values are not unique to each node, the installation process may fail" .

The vm launched by multipass does not have the file /sys/class/dmi/id/product_uuid.

When install k8s with kubeadm, need verify the MAC address and product_uuid are unique for every node.

So, I think it's important to solve this issue.
