Allow to control vdpa device creation and destruction using the vdpa
management tool.
Examples:
1. List the management devices
$ vdpa mgmtdev show

2. Create vdpa instance
$ vdpa dev add mgmtdev pci/0000:3b:00.1 name vdpa0
3. Show vdpa devices
$ vdpa dev show

them seperately.
I will send them again.
