Explicitly import _() in Cinder code

To ensure that logs are properly translated and logged to
the Cinder log files (using the Cinder message catalogs)
we need to explicitly import _() in any python files that
use the _() function.

Enable lazy translation for Cinder

This patch is the final step for getting lazy translation
re-enabled for Cinder.  It removes the use of gettextutils.install()
which is no longer needed with the addition of the explicit import
of _() in all of Cinder's files.  The configuration of 'cinder' catalog
is handled by gettextutils.

The install() function is replaced by gettextutils.enable_lazy() which
properly enables lazy translation when _() or _LX() is used.
