af8292b623 vmm, config, vhost_user_blk: remove "wce" parameter
This config option provided very little value and instead we now enable
this feature (which then lets the guest control the cache mode)
unconditionally.

a7f236b896 ci: Extend snapshot/restore to validate virtio-vsock
Now that snapshot/restore support has been enabled for virtio-vsock, the
corresponding integration test is expanded with some validation that
virtio-vsock supports to be snapshot and restored.

9f2eddd9d8 ci: Fix test_serial_off
The integration test validating that --serial off works correctly was
not properly written as it was using the FW, which by default would use
the kernel command line found in the EFI partition. Unfortunately, this
kernel command line was including "console=ttyS0", which causes the
kernel to try to write to the serial port, even if there's no serial
port being emulated.

The problem is, when no emulation of the serial port is provided, the
default value returned on 0x3f8 is 0, which makes the guest kernel think
that some data needs to be read.

The only way to avoid all this is by ensuring we can control the kernel
command line by removing any occurence of "console=ttyS0" from it.

ba4ec7fce2 ci: Extend snapshot_restore_test with hotplug
There's a simple way to trigger PCI BAR reprogramming for a given
device, by removing it and then hotplugging it back. The Linux kernel
will simply choose to place the BARs at different location than the ones
chosen by Cloud-Hypervisor. By doing so, and creating the snapshot after
this hotplug operation, we can manage to validate that the resource are
correctly restored for a given virtio-pci device.
