Pass temperatures to FATES for hardening frost mortality

[mariuslam]

Description of changes

Calculation of minimum daily temperature, mean daily temperature, minimum yearly temperature, 5 year running mean of the minimum yearly temperature.

Also change of the supercooling of soil in cases where its temperature is below -10degC. This results in a larger variability of the water potential between years in the arctic region. Otherwise water potential reaches minimum each year during winter.

This PR is combined with the PR NGEET/fates#836 in Fates.

Any User Interface Changes (namelist or namelist defaults changes)?

@rosiealice @rgknox wondering about this one as well.

I'm not sure, we plan to cover this topic in a developer meeting when we have a quorum

@mvdebolskiy will work on this when he can. @mariuslam has finished his PhD and has moved on.
