This changes OS::Nova::Server resource to use
translation rules to resolve name_id properties.
As most of the tests in test_server.py and
test_rackspace_cloud_server.py are impacted by this
change, this also changes all the tests to use mock
library. Though the change is very big, it's mostly
mox to mock conversion for the tests.
This reduces the LOC drastically. Some of these test
modules have become very big to manage. We can split
them into smaller ones in the future.
