address radiation balance log messaging

[rgknox]

The radiation scattering code has a good number of logging messages that could use some cleaning up.

There are several locations in the radiation scattering code where we print out messages when unusual behavior occurs, some of this is due to radiation budget error, and some due to other thins like unexpected canopy closure tolerances:

PR #750 brings a diagnostic on radiation solve error. See new field in history here:

https://github.com/NGEET/fates/pull/750/files#diff-03feca0f1df8d3791c0d8f7b6055a0368d5241716d19d6a97c3d227fd6c5ad23R4923-R4926

There are a few things we can do.

1. place in a "debug" logical
2. modify the threshold and apply an endrun so the check only triggers when it is truly unacceptable, and stops the run
3. other?

In the past we saw these balance error messages quite a bit, but with #750 and recent updates, maybe these messages aren't such a big deal.
