too late for rhel7.3,postpone to rhel7.4 test in qemu-ga-win-7.4.3-1

There still are "guest-suspend-disk" and "guest-suspend-ram". Does qemu-ga-win support these two cmd now ?
Reassigen it.

Both of these commands call "GetPwrCapabilities" Windows API in order to check if the command is supported on the guest. The result can depend on the dynamic setting on the guest as well. "guest-suspend-disk" calls it with mode = "GUEST_SUSPEND_MODE_DISK" "guest-suspend-ram" calls it with mode = "GUEST_SUSPEND_MODE_RAM" For "guest-suspend-disk" to be supported the guest should be configured to support S4. For "guest-suspend-ram" to be supported the guest should be configured to support S3. Verified this case in win2012r2.
In win2012r2 guest, I enable Hibernate and execuete "guest-suspend-disk" cmd in host, the guest was shutdown and can remember the info before when i boot it again.
I did not enable S3 in guest, get the error info in host

Description of problem: The output of command {"execute": "guest-info"} includes some unsupported qemu-ga-win commands Version-Release number of selected component (if applicable): Host kernel: 3.10.0-501.el7.x86_64 Qemu-kvm-rhev: qemu-kvm-rhev-2.6.0-22.el7.x86_64 qemu-ga-win: qemu-ga-win-7.3.2-1 How reproducible: 100% Steps to Reproduce: 1. Start a Win2016 x86_64 bit guest with guest agent cmd line: -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x10 \ -chardev socket,id=qga0,path=/tmp/qga.sock,server,nowait \ -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=qga0,id=qga0,name=org.qemu.guest_agent.0 \ 2. After the guest boots up, install virtio serial driver and qemu-ga-win-7.3.2-1 inside the guest 3. In the host, issue qemu-ga-win cmd '{"execute": "guest-info"}': # nc -U /tmp/qga.sock {"execute": "guest-info"} {"return": {"version": "0.12.1", "supported_commands": [{"enabled": true, "name": "guest-set-user-password"}, {"enabled": true, "name": "guest-set-vcpus"}, {"enabled": true, "name": "guest-get-vcpus"}, {"enabled": true, "name": "guest-network-get-interfaces"}, {"enabled": true, "name": "guest-suspend-hybrid"}, {"enabled": true, "name": "guest-suspend-ram"}, {"enabled": true, "name": "guest-suspend-disk"}, {"enabled": true, "name": "guest-fstrim"}, {"enabled": true, "name": "guest-fsfreeze-thaw"}, {"enabled": true, "name": "guest-fsfreeze-freeze"}, {"enabled": true, "name": "guest-fsfreeze-status"}, {"enabled": true, "name": "guest-file-flush"}, {"enabled": true, "name": "guest-file-seek"}, {"enabled": true, "name": "guest-file-write"}, {"enabled": true, "name": "guest-file-read"}, {"enabled": true, "name": "guest-file-close"}, {"enabled": true, "name": "guest-file-open"}, {"enabled": true, "name": "guest-shutdown"}, {"enabled": true, "name": "guest-info"}, {"enabled": true, "name": "guest-set-time"}, {"enabled": true, "name": "guest-get-time"}, {"enabled": true, "name": "guest-ping"}, {"enabled": true, "name": "guest-sync"}, {"enabled": true, "name": "guest-sync-delimited"}]}} {"execute":"guest-network-get-interfaces"} {"error": {"desc": "this feature or command is not currently supported"} 4. Try each commands in the output of cmd '{"execute": "guest-info"}' above Actual results: It's found following commands are not supported by qemu-ga-win: "guest-set-vcpus" "guest-network-get-interfaces" "guest-suspend-hybrid" "guest-suspend-ram" "guest-suspend-disk" "guest-fstrim" "guest-file-flush" "guest-file-seek" "guest-file-write" "guest-file-read" "guest-file-close" "guest-file-open" Expected results: Above unsupported commands of qemu-ga-win should not be included in command {"execute": "guest-info"} output Additional info:
