docs: Creatge backupFTP ACL
  
  @param 	$domain -> Server that this applies to
  @param	$ipBlock -> ipblock that is being granted access
  
  this requires that one type of access be set - and since this is called backuipFTP - I chose the FTP as default
  a second call to set actual desired ACL will be required to set acl to what is desired
  
  @return 	object result set
  
  throws BadMethodCallException if server is not defined
  usual handling for 400/404 errors
