Advanced Watch Dog is an universal monitoring module on VMM side, it can be used to detect network down(VMM to guest, VMM to VMM, VMM to another remote server) and do previously set operation.
for example: send message to admin, notify another VMM, send qmp command to qemu do some operation like restart the VM, build VMM heartbeat system, etc.
It make user have basic VM/Host network monitoring tools and basic false tolerance and recovery solution.

Demo usage(for COLO heartbeat):

In primary node:

-chardev socket,id=h1,host=3.3.3.3,port=9009,server,nowait
-chardev socket,id=heartbeat0,host=3.3.3.3,port=4445
-object iothread,id=iothread2
-object advanced-watchdog,id=heart1,server=on,awd_node=h1,notification_node=heartbeat0,opt_script=colo_opt_script_path,iothread=iothread1,pulse_interval=1000,timeout=5000

In secondary node:

-monitor tcp::4445,server,nowait 
-chardev socket,id=h1,host=3.3.3.3,port=9009,reconnect=1
-chardev socket,id=heart1,host=3.3.3.8,port=4445
-object iothread,id=iothread1
-object advanced-watchdog,id=heart1,server=off,awd_node=h1,notification_node=heart1,opt_script=colo_secondary_opt_script,iothread=iothread1,timeout=10000

Hi,

This series failed the docker-quick@centos7 build test. Please find the testing commands and
