[proxmox_kvm] Implement ciupgrade parameter

[YourSandwich]

Summary

Please implement the ciupgrade parameter that links to package_upgrade: true/false
If cloud-init is used with an ISO file, it can cause the loop device to run out of storage!

Or at least change the default of package_upgrade to false

This parameter is described here: https://pve.proxmox.com/wiki/Cloud-Init_Support#_cloud_init_specific_options
