Make print py3 compatible

[Ji.Wei]

In PY3,

Remove the print "", join the print () function to achieve the same function.

Python 3:

#!/usr/bin/python
# -*- coding: utf-8 -*-
print ("cinder")

print "cinder"

  File "code", line 5
    print "cinder"
                 ^
SyntaxError: Missing parentheses in call to 'print'

[Steve Martinelli (stevemar)]

a quick scan of the keystone code base shows this is not an issue, we only use print in the py3 friendly way. marking this as invalid, re-open if i'm wrong.

    The print '' in python2 was supported. But in python3,
    print '' was error. In python3, recommend using print()

    Clarify test case in common/ring/test_builder

    They use a bare assertRaises(ValueError, ring.RingBuilder, *,*,*), but
    it's not clear which one raises which ValueError(), so I extend them to
    validate the error strings as well.

    Authorise versioned write PUTs before copy

    Currently a versioned write PUT uses a pre-authed request to move
    it into the versioned container before checking whether the
    user is authorised. This can lead to some interesting behaviour
    whereby a user can select a versioned object path that it does not
    have access to, request a put on that versioned object, and this
    request will execute the copy part of the request before it fails
    due to lack of permissions.

    This patch changes the behaviour to be the same as versioned DELETE
    where the request is authorised before anything is moved.
