Disallows reading/writing MSRs in the guest. Can be bypassed with unsafe function on SandboxConfiguration. The goal is to prevent guest state to persist across snapshot-restores.
Will mark ready for review once KVM releases new version, which should include newly added
KVM_X86_SET_MSR_FILTERvm ioctl that this PR depends on, see rust-vmm/kvm#359
