Bug 1153771

Title: The REST Remote Java RuntimeEngine Factory

Describe the issue:
- Our documentation says "RemoteRuntimeEngine engine = RemoteRuntimeEngineFactory.newRestBuilder()" , but even with the BPMS 6.0.3 source code, there is no such method called "newRestBuilder()" inside "RemoteRuntimeEngineFactory" [1] .  Here is the code from the officially shipped source code.
~~~
package org.kie.services.client.api;

import java.util.Collection;

import org.kie.services.client.api.command.RemoteRuntimeEngine;


public interface RemoteRuntimeEngineFactory {

    RemoteRuntimeEngine newRuntimeEngine();

    void addExtraJaxbClasses(Collection<Class<?>> extraJaxbClasses );
}
~~~

Hence, the code sample provided in that section should be updated to look something like this:
~~~
RemoteRestRuntimeEngineFactory remoteRestRuntimeEngineFactory = RemoteRestRuntimeEngineFactory.newBuilder()
					.addDeploymentId(deploymentId)
					.addUrl(url)
					.addUserName(userName)
					.addPassword(passWord)
					.addTimeout(timeOut)
					.build();
				
		RemoteRuntimeEngine remoteRuntimeEngine = remoteRestRuntimeEngineFactory.newRuntimeEngine();		
		KieSession ksession = remoteRuntimeEngine.getKieSession();
...
~~~

I have attached a simple running code (inside the project "RemoteStandaloneRestClient.zip") to demonstrate the same for reference. You can use the attached KJar "RemoteProcessProject-1.0.jar" to deploy it inside Business Central's maven repository to test it.
