quantum metadata proxy does not forward IP properly

[Mark McClain]

The Quantum metadata proxy does not include the forwarded IP address in the header from Quantum to Nova. Additionally, Nova defaults to the requesting server IP which is the proxy IP and not the guest instance local IP.

Thanks to Marton Kiss for finding this bug.

    Pass X-Forwarded-For header to Nova

    fixes bug 1097524

    Add X-Forwarded-For header to the proxied Nova metadata request. Nova
    needs this value to properly answer /latest/meta-data/local-ipv4
    requests.

    Quantum metadata handler now uses X-Forwarded-For

    fixes bug 1097524

    The guest IP address was not properly forwarded from the Quantum
    metadata proxy. This patch adds support in Nova for reading this
    X-Forwarded-For header. Previously, the internal proxy IP was
    mistakenly used exposing internal infrastructure details.
