Error: unknown flag: --trait on local build

[scodeman]

As per #2769 I am trying to build a local integration image and use it in for my integration manifest.
I have the following IntegrationFile.java simple java DSL example with modelines:

// camel-k: language=java
// camel-k: trait=container.enabled=true
// camel-k: trait=container.image=localhost:5000/camelk_test:latest

import org.apache.camel.builder.RouteBuilder;

public class IntegrationFile extends RouteBuilder {
  @Override
  public void configure() throws Exception {

      // Write your routes here, for example:
      from("timer:java?period=1000")
        .routeId("java")
        .setBody()
          .simple("Hello Camel K from ${routeId}")
        .to("log:info");

  }
}

But it fails to local build kamel local build IntegrationFile.java with the following error reported

Modeline options have been loaded from source files
Full command: kamel local build IntegrationFile.java --trait=container.enabled=true --trait=container.image=localhost:5000/camelk_test:latest 
Error: unknown flag: --trait

Note that the dry-run (cf:#2769) kamel run IntegrationFile.java -o yaml call works as expected providing me the following output

The Trait feature is something mainly thought to tune your integration on a Kubernetes platform, reason why it's not present in the kamel local command.
