Add support for annotation indexes

This change modifies the plugin so that it creates annotation indexes.
For each .jar file inside the module a new -jandex.jar file will be
created.

These annotation indexes speed up the deployment of applications and are
required in order to allow the deployment of EJBs inside JBoss modules,
otherwise they are silently ignored.

To preserve backwards compatibility the creation of the indexes is
disabled by default, it can be enabled using the "generateJandex"
parameter as follows:

  <plugin>
    <groupId>org.ovirt</groupId>
    <artifactId>modules-maven-plugin</artifactId>
      <configuration>
        <generateJandex>false</generateJandex>
      </configuration>
    </plugin>
  </plugin>
