    Automatically enable all available languages

    Right now, we have to create at least two patches for each new language that
    becomes available: one to update the tripleo-ui itself, and one to update the
    defaults in the puppet code. This is painful and takes a long time.

    This patch turns things around. Instead of specifying which languages should be
    available, we automatically load all of them, and provide users with a way of
    disabling some of them should they need to. When a new language is imported
    from the translation team into our code, there is no work necessary.

    This is accomplished via Webpack plugin which reads the i18n/locales directory,
    parses the data, and generates a Javascript file with the necessary imports and
    other useful objects. The "languages" setting in the config file is changed to
    "excludedLanguages", and it's a simple list of language abbreviations.

    Futhermore, this patch adds a simple script that verifies that all available
    languages are properly enabled i the constants file.
