AttributeError with cdscan

[pochedls]

Describe the bug

cdscan failing with AttributeError: 'dict_keys' object has no attribute 'append'. This is affecting our ability to access a number of CESM files within CFMIP (since we are not able to produce xmls for the files).

It seems this was documented before and there may be a fix (here). If you'd like, I can attempt a pull request with a fix.

To Reproduce

cdscan -x test.xml /p/css03/esgf_publish/CMIP6/CFMIP/NCAR/CESM2/amip-4xCO2/r1i1p1f1/CFmon/clisccp/gn/v20200124/*.nc

Environment (please complete the following information):

• OS: RHEL 7.8
• CDAT8.2 / Python 3.7.3

Related Issues

• Attribute error on cdscan
• cdscan error with Python 3

@forsyth2 Looks like the cdscan script isn't 100% compatible with python 3.

@forsyth2 & @jasonb5 - this is so helpful - thank you! Will this be included in the next CDAT release?

[pochedls]

Note also that you may be able to close #239 and #256.

@pochedls No problem. This will be in CDAT 8.2.1. Thanks for the links!
