Make st_archive archive CAM+DART output files

[kdraeder]

What is the feature/what would you like to discuss?

Doing data assimilation with CESM+DART generates many new types of output files,
which st-archive should archive, assuming they are named according to CESM conventions.
Many of the new files will be handled by the esp component code, but others are
more closely associated with the geophysical components and should be archived
with their files. We've chosen new file names in such a way that this can be done
with very small changes to
$component/cime_config/config_archive.xml
cime/CIME/XML/archive_base.py
A second small change is to make st-archive handle compressed files (*.gz).
This has no effect on model calculations or existing output.

The changes have been tested in cesm3.0_alphabranch and pushed to my github CAM fork,
except for the ChangeLog, which wants a PR # (or Issue # ).
I'll include more details in the PR, after someone tells me to proceed.
Or I can provide them here.

I don't seem to have permission to select features; Labels, Projects, ...

Is there anyone in particular you want to be part of this conversation?

No response

Will this change (regression test) answers?

No

Will you be implementing this enhancement yourself?

Yes

@kdraeder - Feel free to open a PR to cam_development. We will then perform a review and can work on bringing it into CAM. If you feel comfortable giving me write permission to your fork, I can make the edits we'll need to make directly in your fork. Otherwise, I can open a separate PR which merges your branch into my fork
