Grab failure details from pipeline jobs

- if a job fails, try to get the stages from the job
- if there are stages, get from non-SUCCESS stages all the
  workflow 'nodes' (the commands performed in the stage, like
  'running shell script' or 'echo'), and get the log from the
  failed node only.
- if there are no stages found (assuming that this is
  a pipeline job), get the complete job console output

When a pipeline job failed, the parent job is failed throwing
the exception contaied the found details.
