        Copy the content of the file into memory. The copy operation also weeds out anything that may have been added by the remote batch scheduler. For instance, PBS is prone to add headers and footers.

        input - is the file instance from which to read contents.
        Returns:
        the result code from reading the file

        private int determineExitStatus​(InvocationRecord ivr)
        Determines the exit code of an invocation record. Currently, we will determine the exit code from the main job only.
        Parameters:
        ivr - is the invocation record to put into the database
        Returns:
        the status code as exit code to signal failure etc. 
           0   regular exit with exit code 0
   1   regular exit with exit code > 0
   2   failure to run program from kickstart
   3   application had died on signal
   4   application was suspended (should not happen)
   5   failure in exit code parsing
   6   impossible case
