This commit enables the `share-rw` flag for the image file in s390x.
This enables multiple instances of qemu to share the same image.

Add appendImage function to struct qemuS390x, so that a call of
appendImage results in a call to the appendBlockDevice function of
qemuS390x instead of qemuArchBase.

In this way it is possible to set bridge variable for each arch when
instantiating the hypervisor.

qemu upstream has x-ignore-shared that works similar
to our private bypass-shared-memory. We can use it to
implement the vm template feature.

Let's define agnostic commonkernelRootParams for all hypervisors,
including qemu, firecracker, etc. for now, it has two scenarios,
one for NVDIMM, one for virtio-blk.

Now, template feature can't work on arm64. When using bypass-shared-memory
cap to saving sandbox as a template, new sandbox cloning from the template
will fail. From initial investigation, it maybe a qemu issue. Further
research should be done.
To enable template on arm64, this patch adds a switch to offer the capability
to open or close the bypass-shared-memory cap.
While closing bypass-shared-memory cap, saving vm will occupy more space
and consume more time. So increase 300M for mount size and bump the time
waiting for migration to 10 seconds.

since generic func genericAppendBridges and genericBridges
is also applied for machine type QemuVirt, we use it as implementation
for appendBridges and bridges on aarch64.
since const defaultPCBridgeBus is used in generic func
genericAppendBridges for pc machine, we should define it once
in generic file, instead of redefining it in different
arch-specific files.

This value will be plused to max memory of hypervisor.
It is the memory address space for the NVDIMM devie.
If set block storage driver (block_device_driver) to "nvdimm",
should set memory_offset to the size of block device.

The PR adds the support for s390x.
In the case of CCW devices, the vhost-user devices are not supported.
See #659. An error message is thrown if they tried to be used.
Memory hotplug is not supported on s390 yet and an error message is thrown.
The VirtioNetPCI has been changed to VirtioNet. The generalization
allows to set the VirtioNet to the correct CCW device for s390x.
