Fixes #50 This is done for decoupling device management part from other parts. It seperate device.go to several dirs and files: ``` virtcontainers/device ├── api │ └── interface.go ├── config │ └── config.go ├── drivers │ ├── block.go │ ├── generic.go │ ├── utils.go │ ├── vfio.go │ ├── vhost_user_blk.go │ ├── vhost_user.go │ ├── vhost_user_net.go │ └── vhost_user_scsi.go └── manager ├── manager.go └── utils.go ``` * `api` contains interface definition of device management, so upper level caller should import and use the interface, and lower level should implement the interface. it's bridge to device drivers and callers. * `config` contains structed exported data. * `drivers` contains specific device drivers including block, vfio and vhost user devices. * `manager` exposes an external management package with a `DeviceManager`.
