   2.5. connection: hostkey update and rotation "hostkeys@openssh.com"
   
   OpenSSH supports a protocol extension allowing a server to inform
   a client of all its protocol v.2 hostkeys after user-authentication
   has completed.
   
           byte            SSH_MSG_GLOBAL_REQUEST
           string          "hostkeys@openssh.com"
           string[]        hostkeys
   
   Upon receiving this message, a client may update its known_hosts
   file, adding keys that it has not seen before and deleting keys
   for the server host that are no longer offered.
   
   This extension allows a client to learn key types that it had
   not previously encountered, thereby allowing it to potentially
   upgrade from weaker key algorithms to better ones. It also
   supports graceful key rotation: a server may offer multiple keys
   of the same type for a period (to give clients an opportunity to
   learn them using this extension) before removing the deprecated
   key from those offered.
