Description of changes

PLUMBER2 site simulations need an xml variable similar to DATM_YR_START_FILENAME to identify the end year of the datm forcing file.
We also need changes to taxmode and dtlimit for the PLUMBER2 HIST compsets.

I did a quick look here. I'm fine with this as long as @ekluzek or someone else from the land group approves.

This all looks good and should be brought in.

The settings for DATM_YR_END_FILENAME could be moved from CTSM into here. But, that's a longer term question and it should mainly be done if it would make sense for how CTSM manages the PLUMBER2 sites.

The setting of dtlimit to a high value is what's been done for other cases where we use cycle and the first time sample of the data isn't at 0 UT. But, that's a general problem that should be addressed elsewhere.

@billsacks already approved, and I'm giving my approval now. So I'm merging it in.
