[BUG]: docker event listener fd leak and event lost

[yyuuttaaoo]

Describe the bug
Fd will leak if connection to docker.sock lost.
Details here: fsouza/go-dockerclient#911

Event may lost if lots of container are created concurrently

$ sudo kubectl apply -f deploy.yaml 
$ ./docker-event 2>&1 | tee events.log
2022/10/23 17:11:09.395169 Unofficial: docker event listener start
2022/10/23 17:11:09.395706 Official: docker event listener start
$ sudo kubectl scale --replicas=10 -n sls-test deployment/centos

Result

# grep start events.log | grep Official | grep centos| wc -l
20 #包括pause容器，符合预期
# grep start events.log | grep CRI | grep centos  | wc -l
10 #不包括pause容器，符合预期
# grep start events.log | grep Unofficial | grep centos| wc -l
17 #包括pause容器，漏了3个事件
