    Support overriding oslo localedir too

    Part of fixing bug #995287

    Libraries need to translate strings according to their translation
    domain but they should not override the default _() builtin (which
    should only be installed by the top-level script) and instead should
    gettextutils._().

    To support the case where message catalogs are installed in a
    non-default (and perhaps project-specific) location, we allow the
    default localedir to be override with a project-specific environment
    variable e.g. QUANTUMCLIENT_LOCALEDIR.

    The code makes it seem like OSLO_LOCALEDIR is the env variable we're
    adding but, in fact, update.py magically replaces 'oslo' with the
    project name.
