Add test case for refineDiag and preAnalysis capability in workflow

[singhd789]

Things to do:

• update yaml configurations to include refineDiag and preanalysis info with the postprocessing settings and switches. Ex.:

postprocess:
  settings:
    history_segment:         "P1Y"
    site:                    "ppp-container"
    pp_chunks:               [*PP_CHUNK96]
    pp_start:                *EXP_AMIP_START
    pp_stop:                 *EXP_AMIP_END
    pp_grid_spec:            *GRID_SPEC96
  switches:
    clean_work:              True
    do_atmos_plevel_masking: True
    do_analysis:             False
    do_analysis_only:        False
  preanalysis:
    vitals:
      script: "/path/to/vitals-script"
      input: ['atmos_month', 'aerosol_month']
      do_preanalysis: True
  refinediag:
    ocean:
      script: "/path/to/ocean-script"
      input: ['ocean_monthly', 'ocean_bgc']
      output: ['ocean_refined']
      do_refinediag: True
    aerosol:
      script: "/path/to/aerosol-script"
      input: ['aerosol_month']
      output: ['aerosol_refined']
      do_refinediag: True

• for runner testing: add dummy script that does something really simple
• for local testing:
