Move namelist parameters to paramfile

[linniahawkins]

The PPE team would like to have several parameters that are currently set in the namelist moved to the parameter file:

Jmaxb1 (as a pft dimensioned value, per #2830) baseflow_scalar upplim_destruct_metamorph maximum_leaf_wetted_fraction interception_fraction pot_hmn_ign_counts_alpha decomp_depth_efolding

This is not 100% necessary for us to move forward, our scripting can handle namelist parameter modifications, but it would make things clean and simple.

Thanks for opening this issue and #2830? What's a useful timeline for these? it may be simple enough to create the parameter file that you can use (he said naively), but then it's 2-weeks until b4b-dev comes to main.

Neither of these are necessary for the mini-OAAT (October) nor the first latin-hypercube ensemble (November).

#2831 would be convenient to have by November 1 (but not necessary). https://github.com/ESCOMP/CTSM/issues/2830 will be necessary for history matching (late November).

I should be able to start this soon.

I find that decomp_depth_efolding is already on the parameter file.

I think transferring baseflow_scalar is problematic because its value depends on the lower_boundary_condition chosen and PLUMBER changes its value for some sites as well. Similarly, pot_hmn_ign_counts_alpha is a tuning parameter for fire and depends on the fire method. I've transferred upplim_destruct_metamorph, maximum_leaf_wetted_fraction, interception_fraction, and Jmaxb1 (now jmaxb1 and pft-dimensioned) from the namelist to the parameter file and run the following test subset with bfb results with ctsm5.3.002 (current base for b4b-dev branch).

Next, plan is to convert the parameters in https://github.com/ESCOMP/CTSM/issues/2830 (Jmaxb0, wc2wjb0, r_mort) to pft-dimensioned.
