[PATCH 1/3] qapi/net: Add new QMP command for COLO passthrough

[Zhang Chen <chen.zhang@intel.com >]

From: Zhang Chen <chen.zhang@intel.com>

Since the real user scenario does not need to monitor all traffic.
Add colo-passthrough-add and colo-passthrough-del to maintain
a COLO network passthrough list.
