Aleksei Sviridkin 35df310de1 fix(vm-instance)!: refuse guest memory below KubeVirt's 1M floor
The memory guard refused only zero and negative amounts, while KubeVirt
admission refuses a non-zero amount below 1M. A value such as 500m or
1Ki rendered cleanly and then failed when the VirtualMachine was
applied, two hops away from the value that caused it. The render now
refuses it with the reason.

This is breaking: a memory above zero and below 1M rendered before and
no longer does. Such a VM could not be admitted by KubeVirt either.
