Resumption: SSH job should not raise an error when exporting environment variables in the remote script

Current Situation

• The SSH job exports environment variables of the JobScheduler to the remote script depending on the parameter create_environment_variables = true.
• These environment variables are prefixed with SCHEDULER_MASTER_.
• If the parameter command_delimiter is set then this parameter is also used for the exports which raises an error

For example

• command_delimiter: %%
• command: export test="hallo"; echo $test
• then the following command will be executed

  echo $$%%export SCHEDULER_RETURN_VALUES=sos-ssh-return-values-bae1c60d-7f68-4940-b786-f94edfa836b9.txt%%export test="hallo"; echo $test
  

  and the error

  SOS-SSH-E-160: remote execution reports error: bash: Zeile 0: export: `756%%export': not a valid identifier
  

  is raised.

Desired Behavior

• The exports must be separated with ;.
• The parameter command_delimiter doesn't affects the exports
