NSX Migration: support keystone v3 & other fixes

Browse Source 
- support for keystone V3, and adding domain names as arguments
- add argument to still use keystone v2 for the source connection
  (--use-old-keystone)
- in case network creation fails - print the source network
- skip routers & floatingips creation in case that the source setup
  does not have L3 support
- rename tenant arguments to project
