Currently cinderclient doesn't handle properly incoming and outgoing
encode / decode process. As a solution for this, this patch implements a
decoding process for all data incoming from the user side and encodes
everything going out of the client, i.e: http requests, prints, etc.

This patch introduces a new module (strutils.py) taken from
oslo-incubator in order to use 2 of the functions present in it:

About safe_(decode|encode):

    Both functions try to encode / decode the incoming text using the
    stdin encoding, fallback to python's default encoding if that
    returns None or to UTF-8 as the last option.

    In both functions only basestring objects are accepted and they both
    raise TypeError if an object of another type is passed.

About the general cinderclient changes:

    In order to better support non-ASCII characters, it is a good
    practice to use unicode interanlly and encode everything that has to
    go out. This patch aims to do that and introduces this behaviour in
    the client.

Testing:

    A good test (besides using tox) is to use cinder client with and
    without setting any locale (export LANG=).

When a user Ctrl-C's the client, this will cause a short message to
be printed rather than an ugly backtrace.

This will not catch all instances of this (can still Ctrl-C before
reaching this code, etc.), but it should catch most of them, and those
for long-running sessions.

The specific message was chosen to match one recently added to the
glance client.

This will allow the cinderclient to speak to the v2 rest api if it's
enabled in the cinder config. Includes additional v2 tests as well.

When an exception message contained a non-ascii
character, the str() conversion raised an UnicodeEncodeError.

Avoid this by simply passing the message itself.
Python handles the encoding to locale already.
