      Add a ProxyJump ssh_config(5) option and corresponding -J ssh(1)
      command-line flag to allow simplified indirection through a
      SSH bastion or "jump host".
    
      These options construct a proxy command that connects to the
      specified jump host(s) (more than one may be specified) and uses
      port-forwarding to establish a connection to the next destination.
    
      This codifies the safest way of indirecting connections through SSH
      servers and makes it easy to use.
