net/colo-compare.c: Expose "compare_timeout" to users
The "compare_timeout" determines the maximum time to hold the primary net packet.
This patch expose the "compare_timeout", make user have ability to
adjest the value according to application scenarios.
QMP command demo:
{ "execute": "qom-get",
"arguments": { "path": "/objects/comp0",
"property": "compare_timeout" } }
{ "execute": "qom-set",
"arguments": { "path": "/objects/comp0",
"property": "compare_timeout",
"value": 5000} }
