API returns unicode Location Header

[Alvaro Lopez]

The API is returning some headers encoded as a unicode string, instead of utf8 (against RFC for HTTP). This causes troubles when using nova behind Apache, for example.

This could be considered a duplicate of https://bugs.launchpad.net/nova/+bug/938114 but in a different point in the code.

I will try to submit a patch for this, as well as a check for the headers not being Unicode.

    Ensure that headers are utf8, not unicode

    Although the api.openstack.wsgi.ResponseObject converted the headers to
    utf8 strings to comply with RFC for HTTP this was not enough, since some
    responses that contained unicode strings were returned, causing an error
    when running nova behind an http server like Apache. This change ensures
    that headers are always an utf8 encoded string.
