Fix error message for newer Libvirt/Qemu with UEFI based VMs cannot do VM snapshot #4184
Description
It seems newer libvirt/qemu cannot do snasphot of KVM domains if they use UEFI and the error error: Operation not supported: internal snapshots of a VM with pflash based firmware are not supported is seen in logs. Until the hypervisor side fixes this, this is not a CloudStack problem, however an internal error message is shown; perhaps we can check and throw a correct exception/error message.

Note - this happened only on RaspberryPi4/aarch64, however VM snapshots work on x86/Ubuntu etc.

There are some changes that went in the PR #5297 where it updated the log message and tried to take the snapshot in a different way.
https://github.com/shapeblue/cloudstack/blob/81b7e6e750a581375612b78fbf04ce94da573839/plugins/hypervisors/kvm/src/main/java/com/cloud/hypervisor/kvm/storage/KVMStorageProcessor.java#L1576
So I think it will solve this issue as well, but I could not verify or reproduce it due to lack of specific hardware.
@rohityadavcloud I think we can close this issue based on the changes in PR5297. Please confirm.

Let me close this after checking this on a uefi systems (4.17 on rpi4)
