Improve handling of output to PowerShell channels

    Description

      Current Situation

      • Output Handling
        • Any output created by cmdlets Echo, Write-Output, Write-Verbose, Write-Debug, Write-Warning is written to individual output streams.
        • The PowerShell processor reads streams per output channel and therefore writes output to the log in the sequence:
          • all output to stdout
          • all verbose output
          • all debug output
          • all warning output
          • all output to stderr
        • This behavior does not reproduce the exact sequence in which such output has been created.
      • Only the first line of output created by the Write-Verbose cmdlet is added to the log.
      • Output is added to the task log only. No output is added to the order log.

      Desired Behavior

      • Output Handling
        • The output handling is improved
          • all output by Echo and Write-Output cmdlets is forwarded to spooler_log.info()
          • all output by Write-Verbose is forwarded to spooler_log.debug()
          • all output by Write-Debug is forwarded to spooler_log.debug3()
          • all output by Write-Warning is forwarded to spooler_log.warn()
          • all output by Write-Error is forwarded to stderr (unchanged).
        • The sequence of occurrence of lines of output is considered by the log.
      • All output created by Write-Verbose is added to the log.
      • All output is available with the task log and the order log.

      Workaround

      • Users can use the above-mentioned JobScheduler methods instead of using PowerShell cmdlets to force the correct sequence of occurrence in the log.
        • $spooler_log.info( "some information" ) for output to stdout
        • $spooler_log.debug( "some verbose output" ) for verbose output that is visible depending on the job debug settings
        • $spooler_log.debug3( "some debug output" ) for debug output this is visible with higher debug level settings
        • $spooler_log.warn( "some warning" ) for warnings
        • $spooler_log.error( "some error" ) for errors that are logged and that result in failed execution of the job
