Daniel P. Berrange 30ceaaff5d console: Provide an RFB security proxy implementation
Instead of doing straight passthrough of the RFB protocol from the
tenant sock to the compute socket, insert an RFB security proxy. This
will MITM the initial RFB protocol handshake in order to negotiate an
authentication scheme with the compute node that is distinct from that
used by the tenant.

Based on earlier work by Solly Ross <sross@redhat.com>
