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_.
• Sometimes the export generates a % in the variable name which raises an error
• For example the environment contains

  BASH_FUNC_mc()=() {  . /usr/share/mc/bin/mc-wrapper.sh
  }'
  

  then the error

  ERROR [main] (SOSSSHJob2.java:169) - SOS-SSH-E-160: remote execution reports error: bash: line 1: export: `SCHEDULER_MASTER_BASH_FUNC_MC%%=() {  . /usr/share/mc/bin/mc-wrapper.sh
  }': not a valid identifier
  

  is raised.
