pdp-d feature to simulate aai/mso/vfc in lab

implemented as an optional loadable feature, this
capability enables to bring up simulators used by
junits in a pdp-d lab configuration.

After lab installation, perform:

1. features enable controlloop-util
2. policy start

Now the simulators are opened at ports 6666, 6667, and 6668.

netstat output:
tcp6       0      0 127.0.0.1:6666          :::*                    LISTEN      21562/java
tcp6       0      0 127.0.0.1:6667          :::*                    LISTEN      21562/java
tcp6       0      0 127.0.0.1:6668          :::*                    LISTEN      21562/java

21562 is the pdp-d PID in the lab.
