[CESM2Control] Removing REFCASEs for CESM2.2

Hi all,

In the CESM2.2 development code base, we plan to remove the use of 
REFCASEs for the time being. So B and F compsets will be startup runs by 
default, using the default out-of-the-box initial conditions for each 
component. As we near release of CESM2.2, we will return to using 
REFCASEs for whatever configurations will be scientifically supported in 
that release. (Recall that we have had the same progression in the past 
for other development versions.) The reason for this is that it can be 
hard to maintain compatibility between REFCASEs and an evolving code 
base, especially for CLM.

This change will have NO impact on the CESM2.1 series used for CMIP6.

Please let me know if you have major concerns about this.

Thank you,
