A Protocol wrapper that provides HAProxy support.
This protocol reads the PROXY stream header, v1 or v2, parses the provided
connection data, and modifies the behavior of getPeer and getHost to return
the data provided by the PROXY header.

Wrap an endpoint with PROXY protocol support, so that the transport's
C{getHost} and C{getPeer} methods reflect the attributes of the proxied
connection rather than the underlying connection.
@param wrappedEndpoint: The underlying listening endpoint.
@type wrappedEndpoint: L{IStreamServerEndpoint}
@return: a new listening endpoint that speaks the PROXY protocol.
@rtype: L{IStreamServerEndpoint}
