Add tunnelPortsUpdated variable to help track if tunnel ports were added or not when updates are applied.

Remove three dependent libraries accordingly.

Add isOutgoingDiscoveryAllowed(), isIncomingDiscoveryAllowed(), and getDiscoveryActions() as methods to facilitate changes to discovery procedures easily.
