Description of problem:
Guest agent is not responding: Guest agent not available for now on VM shutdown

When gracefully shutting down a VM in vdsm log i see:

2018-10-07 11:22:17,036+0300 ERROR (Thread-2) [root] Shutdown by QEMU Guest Agent failed (vm:5413)
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 5404, in qemuGuestAgentShutdown
    self._dom.shutdownFlags(libvirt.VIR_DOMAIN_SHUTDOWN_GUEST_AGENT)

    if ret == -1: raise libvirtError ('virDomainShutdownFlags() failed', dom=self)
libvirtError: Guest agent is not responding: Guest agent not available for now

This indicates that the agent is generally available, but not responding at the given moment as Milan explained in BZ 1634765#4


Version-Release number of selected component (if applicable):
vdsm-4.20.42-1.el7ev
4.2.7.2-0.1.el7ev
kernel - 3.10.0-957.el7.x86_64
libvirt-client-4.5.0-10.el7.x86_64

How reproducible:
Almost every VM shutdown

Steps to Reproduce:
1. Start VM on latest 4.2.7.2
2. Shutdown gracefully the VM
3. Check for vdsm log

Actual results:
libvirtError: Guest agent is not responding: Guest agent not available for now


Expected results:
No errors on VM shutdown
