This will be used if the destination server is only accessible through another server/multiple servers
Example: We want to move a website folder from server A to server D, but server C is the only server who has access to server D, and server A only has direct access to server B.In order to have access to server D we need to connect from server A to server B, and from server B to server C.
The requirement of the script is that ssh keys are added between all servers.
