Kubernetes Submit Queue e4724e8ab0 Merge pull request #37109 from Random-Liu/fix-lifecycle-hook-test

Automatic merge from submit-queue

Use netexec container in http lifecycle hook test.

Fixes https://github.com/kubernetes/kubernetes/issues/33636.

The original test is using `"echo -e \"HTTP/1.1 200 OK\n\" | nc -l -p 1234` as a simple http server.

However, it seems that this is not very reliable, which may response before golang thinks it should.
So we get the error:
```
I1106 06:14:13.325397    2096 logs.go:41] Unsolicited response received on idle HTTP channel starting with "HTTP/1.1 200 OK\n\n"; err=<nil>
```

This PR changes the test to use the `netexec` container which is a simple http server written by golang and used in many of our networking e2e test. It should be more reliable.
Mark 1.5 since this is fixing a 1.5 release blocking issue. Mark P0 to match the original issue.
