Port cdat_info functions

[acordonez]

1. cdat_info.download_sample_data_files has been copied to base.io with some minor changes. The Demo 0 notebook and Demo 6 notebook have been run with the updated import statement.
2. cdat_info.provenance.generateProvenance and dependencies have been copied to base.io with some minor changes. I have combined it with the changes that are currently in base.generateProvenance such as the added packages to record. I have removed references to packages like VCS that are no longer PMP dependencies.

I have not copied cdat_info.get_sampledata_path() because there are no references to it in the PMP production code.

I have removed all references to cdat_info except in deprecated code.

Closes #1003

Still waiting on ENSO notebook testing.

Still waiting on ENSO notebook testing.

Pushed update to ENSO notebook. Now need to debug testing failure.

The line throwing the error (106: author = msg["Author"]) is not found in recent versions of esmpy/init.py. I'm trying to figure out what version is getting pulled by the test suite and if there's a way to grab a newer version.
This esmpy issue provides some additional background: esmf-org/esmf#140

Tried pinning the esmpy version to > 8.4.2 but that caused a failure in setting up the test conda environment. Now trying to pin importlib_metadata to an older version that does not raise the error (reference).

[acordonez]

It looks like pinning the importlib_metadata version actually got the test to run successfully. This pin should be removed when we're able to figure out a dev environment that uses a newer esmpy version.

I've created a fix for the build problems in #1107.
