Fix one of the causes of IT flakiness: port conflicts between IPv4 an…

…d IPv6 (#1132)

The integration tests rare flakiness (~1/16 chance) seems to have
multiple causes. This PR fixes one of them - flakiness caused by port
conflicts between IPv4 and IPv6.

In one of the flaky runs,
`QueryAndIngestPipelineTestcase.testWildcardGoesToElastic` panicked
while trying to parse results returned from Quesma (Quesma seemingly
returned something really incorrect!):
```go
resp, bodyBytes := a.RequestToQuesma(ctx, t, "POST", "/unmentioned_index/_search", []byte(`{"query": {"match_all": {}}}`))
var jsonResponse map[string]interface{}
if err := json.Unmarshal(bodyBytes, &jsonResponse); err != nil {
t.Fatalf("Failed to unmarshal response body: %s", err)
}
hits, _ := jsonResponse["hits"].(map[string]interface{}) // PANIC HERE
```

Thankfully I collected a tcpdump from this run, which showed something
strange:

Dumping all containers info from Docker:
```
Quesma container:
  "Ports": {
      "8080/tcp": [{
            "HostIp": "0.0.0.0",
            "HostPort": "32790"
        }, {
            "HostIp": "::",
            "HostPort": "32789"
        }],
  },
Kibana container:
  "Ports": {
      "5601/tcp": [{
            "HostIp": "0.0.0.0",
            "HostPort": "32791"
        }, {
            "HostIp": "::",
            "HostPort": "32790"
        }]
  },
```

Quesma container is bound to `0.0.0.0:32790` (IPv4) and Kibana container
is bound to `::0:32790` (IPv6). When we make requests to Quesma, we
connect to `localhost:32790` - depending on the codepath sometimes it
connects to the correct IPv4 Quesma endpoint, but sometimes it uses IPv6
and erroneously connects to Kibana instead.

This is a bug in testcontainers-go:
testcontainers/testcontainers-go#551
A suggested solution on the linked issue is to bind ports to host only
by IPv4 - this PR applies such workaround.

Note that there are some other sources of flakiness in Quesma's ITs
still left to debug and fix - this only fixes one of them.
