fix #5284: api: clone_vm: assert content type support for target storage

Browse Source 
Asserts whether the target storage supports storing VM images before
cloning a VM and its volumes to the target storage.

Without the check in place, a VMs volumes can be cloned to a storage,
which does not support VM images, but won't be able to start since any
attached volume must be stored on a supported storage.
