debugging tests is a lot easier when you can actually inject stderr
directly through even on successes. Add the pretty tox facility from
nova / tempest-lib into python-nova client as well for functional
tests.

Modules from oslo-incubator already switched to use graduated
libraries (oslo.i18n, oslo.serialization and oslo.utils), so we
should sync latest code and remove outdated modules (gettextutils,
importutils, strutils).

NOTE:
 - module novaclient.openstack.common._i18n should be used only in
   common code
 - module novaclient.i18n designed for usage in novaclient

There was a call from install_venv.py file to post_process method
of InstallVenv class, but this method is not defined in this class
as result it was raising an error. Even when this error doesn't
affect dependencies installation, it is not allowing to display user
information.

Closes-Bug: #1275025

This patchset updates modules based on the config file:
openstack-common.conf

Notes: Some corrections has been added to work with
new files.
  + utils.py: The method safe_decode from strutils.py
    was updated and it is now not necessary to check for
    decode string with py33.
  + base.py: base64 needs a 8-bit string for py33
  + test_shell.py: stdin.encoding is needed for strutils

 - Removes vim headers: It's not needed to set tabstop tons of times,
   this can be done by setting vimrc.
 - I did not update files in common/* and install_venv_common.py because
   these files are sync with oslo.

--flags were not tab-completing under OS X. This was due to the whitespace
collapsing regular expression using the '+' token (meaning one-or-more), which
isn't supported in OS X's version of sed.

Using the more portable '  *' instead of '[  ]+' fixes this.

Additional cleanups

* Remove unecessary embedding of tabs in the file (nova bash-complete doesn't
  emit tabs, so the regular expressions don't have to handle them)

* Restore logic to exclude -h from tab-completion (was lost in last
  tab-completion cleanup)

* Add similar exclude logic for -i

Fixes bug 1266667

The current version of install_venv_common uses the --distribute flag
in its creation of the virtualenv. This causes some upgrade problems
with the new versions of distribute and setuptools. The solution to
those problems is to get off of the distribute bandwagon.
