Initial version of copy-nsxedge

Includes:
 - appliance config overrides (single -> HA and viceversa, alternate datastore selection, fw config etc)
 - Interface reconfiguration via interface spec or interactive
 - Self Signed cert regeneration and fixup (LB VIPs for listener or pool certs, IPSec, SSLVPN are auto regenerated and updated)
 - NAT Rule fixups - any original/translated ip in a user NAT rule will automatically be updated
 - IPSec PSK regeneration (random)
 - listener fixups for LB, IPSec, SSLVPN
 - RouterID fixup - if original is source edge interface ip, is replaced with updated ip.

ToDo:
