multi VM: Multi VMs in serial or parallel

Support for deployment scenarios with any number of VMs
in both serial and parallel configuration. Detailed
content of the patch:

* VswitchControllerPXP class for multi VM support
* pvvpxx and pvpvxx deployments for xx VMs in
  serial respective parallel configuration
* special GUEST_ options expansion to requested
  number of VMs;
* support of GUEST_ options specific macros
  #VMINDEX, #MAC(), #IP() and #EVAL()
* all GUEST specific options are turned to lists
  to be VM specific
* support for VM with 1 NIC
* support for VM with multiple NIC pairs; traffic
  is routed in serial or parallel between NIC paris
  based on deployment scenario
* support for PVVP and PVPV scenarios using VMs
  with different numbers of NICs
