Hi everyone,

So I've created a` NetworkPlugin` that uses a custom HttpTransport. I've also registered it using `NetworkPlugin.getHttpTransports()`. However, when I install this plugin and run ES, it doesn't seem to be using my Http Transport. After looking at `NetworkModule.java`, I found this:

```auto
/** Adds an http transport implementation that can be selected by setting {@link #HTTP_TYPE_KEY}. */
    private void registerHttpTransport(String key, Supplier<HttpServerTransport> factory) {
        if (transportHttpFactories.putIfAbsent(key, factory) != null) {
            throw new IllegalArgumentException("transport for name: " + key + " is already registered");
        }
    }

```

Now it says I have to set `HTTP_TYPE_KEY` to select my HttpTransport. I couldn't find any way to set this. Can someone please tell me how to set this parameter?

Thanks
