Merge PR 775 and 789, and make them conditional on 786

[JurgenZach-NOAA]

This PR is a continuation of PR 775 and incorporates the modifications (removal of some initial outputs) applied in PR 789. In addition, the PR is aligned with PR 786 in that the new kernel execution log file is generated whenever the new "log directory" is uncommented, with the output going into the same folder.

Additions

• Write key parameters, as actually processed by troute, to a separate log file - including, but not limited to:
  ++ MC network
  ++ Diffusive routing (if applicable) and network
  ++ Gages/data assimilation
  ++ Output of results
  ++ Key compute parameters

Removals

Testing
