    shutdown by Qemu Guest Agent if the agent flag in the config is set

    Important: "guest-shutdown" returns only by error a message.

breaks live migration as it always tries to load the vm config - even in case of $nocheck. Also it double loads the config ($conf && $config)

af9110ddd7 Fix in PVE::QemuServer::snapshot_create 
remove the freezefs flag.
If Qemu Guest Agent flag is set in config the vm filesystem will always be frozen,
unless we save RAM.

also remove param freezefs in PVE::API2 snapshot,
because there is no use for it.

So, we need to check that busy is false before doing the block-job-complete.

Also, we force the vm to pause, if it's busy for more than 120s when drive-mirror is at 100%

7183bd9a8f add iothread/dataplane support 
new config option:

iothread: 1|0

This enable iothread/dataplane support, to improve io performance on fast storages

Currently block jobs don't work yet, it's planned for qemu 2.2.
So it's better to not expose yet this option in gui.
