Tanguy Leroux 28099162ab Cluster stats should not render empty http/transport types (#23735) ...

This commit changes the ClusterStatsNodes.NetworkTypes so that is does
not print out empty field names when no Transport or HTTP type is defined:

```
{
"network_types": {
        ...
        "http_types": {
          "": 2
        }
      }
}
```

is now rendered as:

```
{
"network_types": {
        ...
        "http_types": {
        }
      }
}
```
