Simplify global ocean dynamic adjustment test cases

[xylar]

This greatly simplifies the dynamic_adjustment test case in the global_ocean test group. Rather than having to define dynamic adjustment steps in python, they are defined based on config options in a yaml file:

dynamic_adjustment:
  land_ice_flux_mode: data
  get_dt_from_min_res: False

  steps:
    damped_adjustment_1:
      run_duration: 1_00:00:00
      output_interval: 1_00:00:00
      restart_interval: 1_00:00:00
      dt: 02:00:00
      btr_dt: 00:06:00
      Rayleigh_damping_coeff: 1.0e-4

    simulation:
      run_duration: 1_00:00:00
      output_interval: 1_00:00:00
      restart_interval: 1_00:00:00
      dt: 02:00:00
      btr_dt: 00:06:00
      Rayleigh_damping_coeff: None

This is vastly more readable, less error prone and easier to modify during the development process. The flip side is that they are not as flexible, but this seems like a reasonable price to pay. So far, the dynamic adjustment process for all our meshes follows this process. If the ability to modify more namelist options is desirable in the future, we can build this in as well.

Testing

All tests were with the default compilers and MPI on Chrysalis.

I have successfully run the IcoswISC240 and ECwISC30to60 test cases with this branch through dynamic adjustment (the latter required a reduction in the max Haney number, which has been added to #666).

I have also successfully run the pr and quwisc240_for_e3sm suites.

Other meshes are expensive to test so they will be fine-tuned as part of their respective PRs (#667, #668, #669, etc.)
