kata_proxy: Set Setsid to true when exec kata-proxy

There is an issue that ctrl-c stop vmcache server will stop all containers that its VM is created by it. The cause is kata-proxy and vmcache server use same tty, for example: ps -e | grep kata 3617 pts/5 00:00:00 kata-runtime 3636 pts/5 00:00:00 kata-proxy Ctrl-c will send signal to both kata-proxy and vmcache server. Then the containers that its VM is created by this vmcache server will quit with it. Set Setsid to true when exec kata-proxy to handle this issue. Fixes: #1726 Signed-off-by: Hui Zhu <[email protected]>
