Print settings

[forsyth2]

Print settings in each generated script. Resolves #121

@golaz This code prints the settings for the E3SM Diags tasks. If you like this format, I can implement the same thing for the other tasks and merge.

Example output: e3sm_diags_atm_monthly_180x360_aave_model_vs_obs_1985-2014.settings:

Note: If we keep the settings printing outside the if not c["dry_run"]: block (which I think would be useful as it would allow dry-run tests to produce the list of settings), then we'd also need to update the expected files for the zppy/tests/integration/test_bash_generation.py test.

[forsyth2]

Yes, keep the printing outside the if not c["dry_run"]: block, so settings always print.

We may want to create a function for printing the settings at some point, but not necessary now.

zppy/tests/integration/test_bash_generation.py will need to have expected files updated.

Looks great!
