Transactional transfer option should be enabled or disabled when used with a jump host

Current Situation

• By default YADE performs transactional transfer when used with a jump host, which means YADE transfers files with a atomic suffix e.g. ~
• Once transfer is completed, files are renamed to there original name e.g. ~a.txt to a.txt
• Some restrictive target SFTP/FTP servers, where users do not have permissions to perform Move/Delete operations, the YADE transfer fail.
• transactional=false or atomic_suffix=<empty string> do not have any effect on default transactional transfer.
• In case of the operation copytointernet the parameter transactional=false is not transferred to the jump_command script jade.sh

Desired Behavior

• It should be possible to disable the default behavior of transactional transfer by use of the parameter transactional=false

Maintainer Note

• Receiving or sending files via a jump host needs a transactional transfer
• It is not possible to change this setting.
• A transactional transfer needs an atomic_suffix or atomic_prefix which can be configured. Per default a atomic_suffix=~ is used.
