Network host option works not with expected behavior

[Bablzz]

Hello everyone!

Thanks for excellent library!

I've got stack an one problem. Maybe you can help me. Maybe I don't understand something

Thanks in advance!

PS. Library v.0.0.10

Describe the bug
Network host option works not with expected behavior

To Reproduce

func TestContainerWithHostNetworkOptions(t *testing.T) {
	ctx := context.Background()
	gcr := testcontainers.GenericContainerRequest{ContainerRequest: testcontainers.ContainerRequest{
		Image:    "nginx",
		Networks: []string{"host"},
	},
		Started: true,
	}

	nginxC, err := testcontainers.GenericContainer(ctx, gcr)
	if err != nil {
		fmt.Errorf("Error %s", err)
	}

	host, err := nginxC.Host(ctx)

	resp, err := http.Get("http://" + host + ":80")
	if err != nil {
		t.Error(err)
	}
	t.Log(resp)
}

=> golang.org/x/sys/unix.ECONNREFUSED (111)

Expected behavior
When I use Networks: []string{"host"} I expect the same behavior as docker run --net host

** docker info **
output of the command:

Additional context
I've tried to add option like ExposedPorts but I've got the same error.
But if I delete Networks "host" options and add ExposedPorts it works

Thank you for providing the test!
I will try to figure out what is going on next week

@gianarb I've debugged a little bit and I've founded out something.
Example

docker run --net host ...
docker inspect ...

I see

        "HostConfig": {
            "Binds": null,
            "ContainerIDFile": "",
            "LogConfig": {
                "Type": "json-file",
                "Config": {}
            },
            "NetworkMode": "host"

"NetworkMode": "host"

When I use this library I see

        "HostConfig": {
            "Binds": null,
            "ContainerIDFile": "",
            "LogConfig": {
                "Type": "json-file",
                "Config": {}
            },
            "NetworkMode": "default"

"NetworkMode": "default"

I can make PR if you don't mind.
