DM:tools: add acrnctl tool

The acrnctl can help user to create, delete, launch and stop UOSs,
To see what it can do, just run:
	# acrnctl
or
	# acrnctl help
you may see:
	support:
        	list
        	start
        	stop
        	del
		add
	Use acrnctl [cmd] help for details
There are examples:
(1) add a VM
    Each time you can just add one VM. Suppose you have an UOS
    launch script, such as launch_UOS.sh
    you can run:
	# acrnctl add launch_UOS.sh -U 1
	vm1-14:59:30 added
    Note that, launch script shoud be able to launch ONE UOS. If
    it fail, it is better to print some error logs, to tell user
    the reason, so that he knows how to solve it.
    The vmname is important, the acrnctl searchs VMs by their
    names. so duplicated VM names are not allowed. Beside, if the
    launch script changes VM name at launch time, acrnctl will
    not recgonize it.
(2) delete VMs
	# acrnctl del vm1-14:59:30
(3) show VMs
	# acrnctl list
	vm1-14:59:30            untracked
	vm-yocto            	stop
	vm-android		stop
(4) start VM
    you can start a vm with 'stop' status, each time can start
    one VM.
	# acrnctl start vm-yocto
(5) stop VM
    you can stop VMs, if their status is not 'stop'
	# acrnctl stop vm-yocto vm1-14:59:30 vm-android
