Code Issues Proposed changes

Port test_ipv6 to py3 and simplify to_global()

Browse Source 
* ipv6.account_identifier.to_global(): on Python 3, encode project_id
  to UTF-8.
* Simplify also to_global(): replace netaddr.EUI(mac).words with
  netaddr.EUI.value to avoid conversions (int => str (hex) => int).
* tests-py3.txt: run nova.tests.unit.test_ipv6 on Python 3
