Using Named target server without SSL

[akshat-spot]

I have a proxy that checks the AccessToken and passes through the request to the backend server. It works well when the `<TargetEndpoint>`uses the URL of a GCP internal load balancer. 

```

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<TargetEndpoint name="default">

<Flows/>

<PostFlow name="PostFlow">

<Request/>

<Response/>

</PostFlow>

<HTTPTargetConnection>

<URL>http://10.x.x.x:80</URL>

</HTTPTargetConnection>

</TargetEndpoint>
```

I want to use the same proxy in multiple environments, so I setup a named target server that uses the same GCP internal load balancer IP as the host and has SSL disabled. 
```
{
host: 10.x.x.x,
ssl: disabled,
protocol: http,
port: 80,
name: named-target-1
}
```

When I this named target server in my proxy using a load balancer, it fails with the following error
```
Unrecognized SSL message, plaintext connection?
```

Here's the proxy config with named server
```

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<TargetEndpoint name="default">

<Flows/>

<PostFlow name="PostFlow">

<Request/>

<Response/>

</PostFlow>

<HTTPTargetConnection>

<SSLInfo>

    <ClientAuthEnabled>false</ClientAuthEnabled>

    <Enabled>false</Enabled>

    <IgnoreValidationErrors>true</IgnoreValidationErrors>

</SSLInfo>

<LoadBalancer>

    <Server name="named-target-1"/> 

    </LoadBalancer>

    </HTTPTargetConnection>

</TargetEndpoint>
```

As shown above, I've disabled SSL in the HTTPTargetConnection config too. 

Aim is to pass the request over insecure (HTTP) connection to the internal load balancer that runs a K8s service behind it.
