Python 2 has been deprecated for almost two years, and has not been
guaranteed to work with glance_store for a while. This patch removes all
traces of six, unicode strings and Python 2 tweaks.

Revive the S3 driver that was supported up to Mitaka and add multiple
store support to correspond with the features added to glance_store from
Newton to U cycle. In addition, the use of the S3 SDK used by the Mitaka
S3 driver has been deprecated, so this implementation will be changed
to use the new version.

This addresses some nits from I1f2e8fa61d6dfecd8395a1f894f74ec5bcb5573c
that were not worth holding up that review to address.

Added supporting logic to configure, manage and use multiple stores
of the same or different type/scheme. Added new config option
'default_backend' which will be used to specifiy default store
to which image will be stored.
Added support for file and rbd store. The default behavior is
maintained for backward compatibility.

Currently we use asserts for uri validation, which is not good
practice because assert will be deleted from optimized code.
We must use exceptions in such cases.

As per the deprecation indicated in change
I139c36c2d591a55f0f91ea32efa963f80c28e444 , we are on track to removing
the S3 driver from glance_store in Newton.
The process of maintainers for individual drives was initiated in [1].
However, S3 doesn't have a maintainer and has been deprecated in Mitaka.
This commit intends to remove the S3 driver completely from the
glance_store source tree. If required, we recommend that this driver be
maintained outside of the glance_store source tree until you or someone
you know intend to support the code for long term. In the later case, we
hope that you will welcome our spec process to help plan the project
priorities.

Move from oslo.config to oslo_config. This change could prevent glance
failed by "NoSuchOptError: no such option: glance_store" triggered in
verify_default_store() error when startup [0].
The root cause is that when we import oslo.config.cfg (when importing
glance_store in glance context) first than oslo_config.cfg, global
oslo.config.cfg.ConfigOpts object (CONF) in glance_store code is a
different object (and type) than oslo_config.cfg.ConfigOpts object in
glance code, so register_opts() of glance_store registered all store
needed options to a separated ConfigOpts object but glance used one.
With change I30ecbf8f9de77496fcb643c7ad9738d79ad359f0) glance is using
oslo_config namespace now, so before release new glance_store, we need
merge this change in.
A clear and simpler example as following:
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
>>> from glance_store import backend
>>> from glance.common import config # we do this importing order for
pep8 required in now code.
>>> config.CONF == backend.CONF, config.CONF, backend.CONF
(False, <oslo_config.cfg.ConfigOpts object at 0x7f4e4cd18690>,
<oslo.config.cfg.ConfigOpts object at 0x7f4e4e521d50>)
# Renew python session.
>>> from glance.common import config
>>> from glance_store import backend
>>> config.CONF == backend.CONF, config.CONF, backend.CONF
(True, <oslo_config.cfg.ConfigOpts object at 0x7fc355937450>,
<oslo_config.cfg.ConfigOpts object at 0x7fc355937450>)

1. Changed drivers to prevent using global CONF but access it from
client by interface.
2. Corrected swift driver to involve options from swift driver utils,
allow glance_store exports and registers them for client.
3. Added missing test cases for the functions of swift driver util.

Given the existing, known issues, with python namespaces, pip and
setuptools, we've decided to rename glance.store into glance_store.
