c22fb87b05 ch_driver: Add domainSave, domainSaveFlags callbacks
Implemented save callbacks. CH's vmm.snapshot API is called to save the
domain state. The path passed to these callbacks has to be of directory
as CH takes dir as input to snapshot and saves multiple files under it.

2c1f34a2bb ch: use payload api to send kernel details
Starting with v28.0 cloud-hypervisor requires the use of "payload" api to pass
kernel, initramfs and cmdline options. Extend ch driver to use the new
api based on ch version.

51ff124d9c virCHDriverConfig: Drop @uri member
This member is unused (apart from only being set in
virCHDriverConfigNew()), and never freed really (leading to a
memleak).

56fbabf1a1 Add basic driver for the Cloud-Hypervisor
Cloud-Hypervisor is a KVM virtualization using hypervisor. It
functions similarly to qemu and the libvirt Cloud-Hypervisor driver
uses a very similar structure to the libvirt driver.

The biggest difference from the libvirt perspective is that the
"monitor" socket is seperated into two sockets one that commands are
issued to and one that events are notified from. The current
implementation only uses the command socket (running over a REST API
with json encoded data) with future changes to add support for the
event socket (to better handle shutdowns from inside the VM).

This patch adds support for the following initial VM actions using the
Cloud-Hypervsior API:
 * vm.create
 * vm.delete
 * vm.boot
 * vm.shutdown
 * vm.reboot
 * vm.pause
 * vm.resume

To use the Cloud-Hypervisor driver, the v15.0 release of
Cloud-Hypervisor is required to be installed.

Some additional notes:
 * The curl handle is persistent but not useful to detect ch process
 shutdown/crash (a future patch will address this shortcoming)
 * On a 64-bit host Cloud-Hypervisor needs to support PVH and so can
 emulate 32-bit mode but it isn't fully tested (a 64-bit kernel and
 32-bit userspace is fine, a 32-bit kernel isn't validated)
