Bug 6833: InterVpnLink FIB routes not populated when no VM on VPN

 + FIB table's flow that send the packet to BGP router for BGP-exported
   route is not being populated when there is an InterVpnLink
   but there are no VMs in the included VPNs.

 + At InterVpnLink creation, it checks if the VPN Operational data is
   ready, and wait 20 seconds for it to be ready.

 + Fix is based on calling method fibManager.populateFibOnNewDpn()
   when the InterVpnLink is created. Even if there are no real VPN
   Interfaces installed on any DPNs, the InterVpnLink installs 2 fake
   VpnInterfaces on the selected DPN(s). This wasn't triggering the
   'createFibEntries' as real VpnInterfaces did.

 + Also, solves the problem of creating an InterVpnLink when the
   Operational Data of a VPN is not ready yet

    - New class VpnOpDataNotifier that offers methods like waitForXXXX,
      to which other classes like VpnInterfaceManager or
      InterVpnLinkListener can subscribe to. There must be only object
      of this type per module, and it must be injected to the interested
      classes via Constructor
