py33: unknown encoding: base64 Edit

Python 3 doesn't support str.encode('base64'), we should use the
module "base64" instead.

if we have a valid auth token, use it instead of generating a new one

If authenticating with a valid token (i.e., token auth, not
username/password auth), novaclient would instruct keystone to issue
a new token with an identical expiry to the one used, and pivot
onto it.  This makes it appear as though Nova is leaking Keystone
tokens.

Since there's zero benefit to issuing a new token that is ostensibly
identical to the perfectly good token used to authenticate, make
novaclient keep using the token it already has after successful
validation, and not issue a new one.

This patch set adds a new pair of tests to the
AuthenticateAgainstKeystoneTests class, which parrot the current
authentication pass/fail tests, but exercise the new code paths

Also adds a fix by Joe Gordon to make os_cache work correctly.

Add-in some re-auth logic when using os_cache

When using os_cache for the auth_token, if username and password
are available when a token fails to validate/authenticate, attempt
a reauth behind the scenes.

The helper object for stashing the auth_token doesn't handle flushing
the cache.  This is valid behavior because the result would be the
same as if a bad username/password were issued (401 Unauthorized).

py33: uuid verification in find_resource()

1. strutils.safe_encode() return "bytes" in py33.
2. find_resource() makes use of uuid.UUID() to verify the given
uuid argument, uuid.UUID() will trigger TypeError when input is
"bytes".

so, decode the bytes before uuid.UUID() while run in Python 3.

Add shelve/unshelve/shelve-offload command

The "shelve" API, which powers off and snapshots a vm instance, has been
implemented by Nova-server side.
In addition, thare are two relational API "unshelve" and "shelveOffload".
This patch adds three commands for using these APIs.

py33: align the order of parameters for urlencode()

In Python 3, hash randomization is enabled by default. It causes the
iteration order of dicts and sets to be unpredictable and differ across
Python runs.

In the test case, the fixed expecting string will not match the test
result, it is relying on the dict order.

This change transforms the input dict to a sequence of two-element list,
with fixed order, and update the related expecitng string.

py33: 'str' does not support the buffer interface

Binary I/O expects and produces bytes objects. If sys.stdout is
assigned to io.BytesIO, print() output it stdout by default, then
there will be "TypeError".

For this case, mock.patch() decorator can not work well casually.
So this patch just update the six.StringIO() for stdout/stderr.

py33: sort dict for test_add_floating_ip_to_fixed

In Python 3, hash randomization is enabled by default. It causes the
iteration order of dicts and sets to be unpredictable and differ across

Sort the list and update the expecting result.
