title: Register annotated CDI beans without beans.xml
body: <p>we have some annotated CDI beans and we need to register these beans without beans.xml. Surely, we are using CDI extension mechanism but I couldn't find a simple way to register beans. When we use beans.xml we just say "all" and it registers all annotated beans. What about in CDI extension ?</p>
  
  <p>For example,</p>
  
  <pre><code>abc.scanPackage("com.abc") // register all annotated beans in com.abc package
  </code></pre>
