    Return correct href if bind_host is 0.0.0.0.

    The existing code returns incorrect href= in the root document (aka
    "version" document) if the default configuration is used. If a remote
    system accesses Glance API, the netspec of href= contains 0.0.0.0,
    which cannot be used for further remote accesses. This happens because
    attempts to use local configuration or the bind address to reconstruct
    URLs are futile.

    The correct way resolve this problem is to use the Host: header
    of the HTTP request. As a bonus, it works with IPv6, should we ever
    support it.
