Using existing modules via new @UseModules annotation.

Example:
```java
@RunWith(JukitoRunner.class)
@UseModules({ FooModule.class, BarModule.class}
public class MyTest {
  // Tests methods  
}
```
The example is equivalent to the following _inner static module class_ approach.
```java
@RunWith(JukitoRunner.class)
public class MyTest {
  static class Module extends JukitoModule {
    @Override
      protected void configureTest() {
        install(new FooModule());
        install(new BarModule());
      }
    }
  // Test methods
}
```
