This patch adds new class distributed_device which is responsible for initializing HW device and it is shared between all cpus. Old device class responsibility becomes managing rx/tx queue pair and it is local per cpu. Each cpu have to call distributed_device::init_local_queue() to create its own device. The logic to distribute cpus between available queues (in case there is no enough queues for each cpu) is in the distributed_device currently and not really implemented yet, so only one queue or queues == cpus scenarios are supported currently, but this can be fixed later. The plan is to rename "distributed_device" to "device" and "device" to "queue_pair" in later patches.
