Creating new flags to control monotonic flux limiter (#1039)

* Creating new flags to control monotonic flux limiter and the IF statement fix for the spikes found in CAM.

* Removing no-longer-necessary logical l_mono_flux_lim.

* Adding requested changes from PR (intent statements and editing error statement).

* Accidentally set flag to false. Changing to true.

I am adding cloudy_updraft_frac and cloudy_downdraft_frac as
outputs to the calculate_w_up_in_cloud code.

These fields are non-interactive for the standard set of cases.
Thus, all cases are bit-for-bit identical.

However, for the w_up_in_cloud and w_down_in_cloud results themselves,
it is possible that results might not be bit-for-bit since
the location of the max(eps, ...) clipping in the denominator
is changed.  However, results should not be appreciable different.

I forgot to add cld_updr_frac and cld_downdr_frac to all_stats.in
in the last commit.
