Incorporate testing documentation from google doc

[billsacks]

We currently have a google doc with some testing documentation:

https://docs.google.com/document/d/1oDNFPzw8bFbuyY129vX6-RJG-C9ZNUs-O1x2uVjSO4M/edit

CESM's old README file (from when CESM was in svn) pointed to this with the following text:

The most current process for updating and testing CESM versions is documented in a shared
NCAR/UCAR google document at:

https://docs.google.com/a/ucar.edu/document/d/1oDNFPzw8bFbuyY129vX6-RJG-C9ZNUs-O1x2uVjSO4M/edit?usp=sharing

I haven't looked through this documentation very carefully. It's quite possible that some of it is out-dated at this point. But some of it may be worth maintaining.

We should consider moving relevant parts to either the Wiki or other documentation within this repository.

@billsacks this document is still very relevant and @fischer-ncar has been keeping it up-to-date. This is very specific to our (CSEG) workflows so I'm not sure if it belongs in this CESM public repo. Some of it, however, should be extracted and added to the CIME rst documentation section 4 on testing.

Personally, I don't see a reason not to move this information into the wiki, other than the valid issue of the time it would take to convert it. While most people wouldn't be interested in this, I think it doesn't hurt to have this sort of thing documented, and it seems helpful to keep all of this in one place rather than having a separate google doc outside of the repo.

But I don't feel strongly enough about it to push hard if you and/or @fischer-ncar would rather keep it separate.

This was mistakenly auto-closed.
