Description of changes

addition of namelist based skip restart functionality to dlnd, docn, drof, dwav

Specific notes

New science use cases require the ability to have skip restart functionality that is togged by namelist input for docn/prescribed sst.
As a result, I have also added this to dlnd, drof and dwav. dice cannot have this since its prognostic and needs the restart.
The same also holds for dlnd. New xml variables have been introduced in cime_config for dlnd, docn, drov and dwav so that this behavior can be togged.

Contributors other than yourself, if any: None

CDEPS Issues Fixed: None

Are there dependencies on other component PRs (if so list): No

Are changes expected to change answers: bfb

Any User Interface Changes (namelist or namelist defaults changes): Yes - for dlnd, docn, drof and dwav new namelist variables skip_restart_read

Testing performed (e.g. aux_cdeps, CESM prealpha, etc):
Verified that the following still restarted exactly when the DXXX_RESTART_READ xml variable was set to TRUE.
ERS_Ld3.f45_g37_rx1.A.cheyenne_intel
ERS_Ld3.f09_f09_mg17.1850_SATM_DLND%SCPL_SICE_SOCN_SROF_SGLC_SWAV.cheyenne_intel
ERS_Ld3.f09_f09_mg17.1850_SATM_DLND%SCPL_SICE_SOCN_SROF_SGLC_SWAV.cheyenne_intel

Hashes used for testing: cesm2_3_alpha09c with cdeps0.12.58

skip_restart_read=false is a double negative, I think that we should avoid it if possible. Also why can't this logic be added to dshr_mesh_init which is already shared code which sets the read_restart variable. Doing this would avoid a lot of code duplication.

@jedwards4b - thanks for reviewing this. Agreed about the double negative - but then I have to change it back in datm.
dice and som cannot use this flag - since they must always have restart. That's why it cannot go in dshr_mesh_init.

@mvertens i tested this and datm_cdeps_control_cfsr UFS RT is passing.

@uturuncoglu - thank you for testing this!
