Delete last bits of bin/.  With the move to entrypoints these aren't
needed anymore.

Update CONF.bindir to default to
  os.path.join(sys.prefix, 'local', 'bin')

As part of the move of plugins to entrypoints, take advantage of the
entrypoints based console scripts, which will make our command line scripts
available for unittesting.

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')
 無効な syslog ファシリティ
 >>> gettext.install('nova', unicode=1, localedir='/opt/stack/nova/nova/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 Nova, we have taken a shortcut to avoid having to call it
explicitly from each script and instead call it from nova/__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 nova code (indeed, if we wanted to
support this, Nova 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
nova.openstack.common and this in turn causes gettext.install('nova')
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.

nova.flags is no longer needed except to load nova config options shared
across multiple daemons.

This removes nova.flags from the bin programs and makes sure that
nova.flags is imported in nova.config for now.

Use the global CONF variable instead of FLAGS. This is purely a cleanup
since FLAGS is already just another reference to CONF.

We leave the nova.flags imports until a later cleanup commit since
removing them may cause unpredictable problems due to config options not
being registered.

The flags module will eventually be removed and this is a first step
towards that.

I only just moved logging from nova to common, so behavior should remain the same.
