> This was discovered while testing upgrading an SSL enabled cluster from 3.0 
> to 4.0.  The 3.0 cluster was configured to only listen on the ssl storage 
> port. When the upgraded 4.0 node started it received a gossip messsage that 
> triggered a shadow round before it had correctly set the messaging versions 
> for the other endpoints.
> Sending the message created the connection, but because the endpoint 
> defaulted to {{VERSION_40}} the initial connect attempt was to the regular 
> {{storage_port}}.  The 3.0 node was only listening on the 
> {{ssl_storage_port}}, so the connection was refused and the 
> {{OutboundConnection.onFailure}} handler was called.  As the shadow
> gossip round had queued up a message, the {{hasPending}} branch was followed 
> and the connection was rescheduled, however the port is never recalculated as 
> the original settings are used so it always fails.
> Meanwhile, the node discovered information about peers through inbound 
> connection and gossip updating the messaging version for the endpoint which 
> could have been used to make a valid connection.
