ooi generates incorrect urls behind ssl terminator

[Enol Fernández]

ooi generates URLs for the objects as http when being served behind of a ssl terminator such as HAProxy. ooi assumes http because it is not aware of the SSL.

Other OpenStack services have a secure_proxy_ssl_header option with the name of the HTTP header where the used scheme for the URLs is defined. ooi should have a similar setting.

    Add option to handle SSL termination proxies

    ooi needs to return URLs of objects matching the URL scheme used
    for serving the application even if ooi is behind a SSL termination
    proxy.

    A new configuration variable "ooi_secure_proxy_ssl_header" that
    defines the HTTP header that can be used to update the wsgi.url_scheme
    environment variable. Typical value for this variable is
    'HTTP_X_FORWARDED_PROTO'.
