QEMU: Use adaptive timeout for connecting to monitor
</summary>
<description>
When starting qemu, libvirt waits for qemu to create the monitor
socket which libvirt connects to. Historically, there was sharp 30
second timeout after which the qemu process was killed. This
approach is suboptimal as in some scenarios with huge amounts of
guest RAM it can take a minute or more for kernel to allocate and
zero out pages for qemu. The timeout is now flexible and computed by
libvirt at domain startup.
