282. vm2vm vhost-user/virtio-user test plan

282.1. Description

This test plan test several features in VM2VM topo: 1. Split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test. 2. Packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vectorized path (ringsize not powerof 2) test. 3. Split ring and packed ring vm2vm test when vhost enqueue operation with multi-CBDMA channels.
