Default language for API responses has changed

[Brad Pokorny]

With the delayed message translation changes in oslo, if a language isn't specified in the Accept-Language header on API requests, the default language is now set to en_US. It used to default to the language of the server side if the Accept-Language header was not provided.

This behavior should be changed in the delayed message translation support to use the language of the server.

    Use system locale when Accept-Language header is not provided

    Remove en_US as the default language when no header is provided, and use
    None instead. Upon translation None will be defaulted to system as it
    was before the translation changes.

    Fixes bug: #1214476
