Part of fixing bug #995287
Syncs these two commits from oslo-incubator:
Support overriding oslo localedir too
Add a gettextutils.install() helper function
to get a new gettextutils.install() function which allows the default
localedir to be overwritten via an environment variable.
Note that gettextutils.install() must be called before any other cinder
modules are imported since some modules attempt to translate strings
at import time (e.g. in cinder.flags). This is broken and inefficient,
but fixing it involves adding something like sphinx's l_() function and
would be very invaisve.

The gettext.install() function installs a builtin _() function which
translates a string in the translation domain supplied to the install()
function. If gettext.install() is called multiple times, it's the last
call to the function which wins and the last supplied translation domain
which is used e.g.
>>> import os
>>> os.environ['LANG'] = 'ja.UTF-8'
>>> import gettext
>>> gettext.install('keystone', unicode=1, localedir='/opt/stack/keystone/keystone/locale')
>>> print _('Invalid syslog facility')
n無効な syslog ファシリティ
>>> gettext.install('cinder', unicode=1, localedir='/opt/stack/nova/cinder/locale')
>>> print _('Invalid syslog facility')
Invalid syslog facility
Usually this function is called early on in a toplevel script and we
assume that no other code will call it and override the installed _().
However, in Cinder, we have taken a shortcut to avoid having to call it
explicitly from each script and instead call it from cinder/__init__.py.
This shortcut would be perfectly fine if we were absolutely sure that
nova modules would never be imported from another program. It's probably
quite incorrect for a program to use cinder code (indeed, if we wanted
to support this, Cinder code shouldn't use the default _() function) but
nevertheless there are some corner cases where it happens. For example,
the keystoneclient auth_token middleware tries to import cfg from
cinder.openstack and this in turn causes gettext.install('cinder') in
other projects like glance or quantum.
To avoid any doubt here, let's just rip out the shortcut and always
call gettext.install() from the top-level script.
However, there's a bit of an annoying detail here - by default,
nosetests starts in the current directly and tries to import all modules
it finds to look for tests. Without the _() builtin installed, importing
some modules like cinder.flags will fail.
Since it only ever makes sense to load tests from the cinder/tests dir,
we can ask nose to do that by using the --tests argument via setup.cfg.
Note, this means that if you previously did this:
$> tox -- cinder.tests.foo cinder.tests.bar
then you must now do this:
$> tox -- --tests cinder.tests.foo,cinder.tests.bar

As a work-around to deal with bug 1075838, we modified
monkey_patch in the Cinder binaries. The root cause of the
issue is/was actually a bug in eventlet but this was a quick
work-around.
Since the change Change-Id: I69ba75136e32e95c6fdf108f0c4fe21a5e3bdbe6
to do this landed, the problem has also been addressed in Keystone.
So, let's revert this patch to get back the greenthread performance
that we may have lost with this change. For now, everything should
be addressed as long as we don't implement multi api worker in Cinder,
if we do and the evenlet fix hasn't been released we'll need to turn
the modification back on for bin/cinder-api.

The openssl popen call to verify the token returns an error code
of 2 when a file doesn't exist. Normally this is caught and the
relevant file is downloaded, but monkeypatching os causes this
error code to be eaten and cinder to return a 401. Note that this
is likely a race condition that depends on exactly when greenthreads
are switching that is causing the return code from Popen to get
overwritten.
It is possible that this is exposing an underlying bug in eventlet
but the workaround is simply to make sure that we don't monkeypatch
os.

- We are not using openstack.common.notifier just yet so handedit
openstack.common.log to use cinder.notifier now.

Cherry picks 00786bc from Nova.
Implements blueprint cfg-global-object
Replace cinder.flags.FLAGS with openstack.common.cfg.CONF.
In future, we can do a s/FLAGS/CONF/ across the codebase.
