Added JPDA options to instance

Maybe this is already in here and I just don't know where...but this adds the ability to enable remote debugging. With this enabled, you will be able to attach a debugger process from within your IDE (Eclipse, NetBeans, IntelliJ, etc)

**Example Usage:**
```puppet
tomcat::instance {"my-instance":
  ensure         => present,
  jpda           => true,
  jpda_port      => "8000",
  jpda_transport => "dt_socket",
}
```
