Subject: [PATCH] Turn IAU off during staging job for cold start experiments
(#3215)
Resolve a bug related to IAU when cold-starting an experiment.
The model start time for non-atmos ICs were incorrectly being reduced by 3hrs
for cold-started experiments. While a user may want IAU on (`DOIAU=YES`), the
IAU switch should be set to "NO" for the staging job when it is cold-started.
Resolves #2890
Resolves #2865
