Cleanup old code

[ian-noaa]

We have some unused code that can be removed now that we've switched ingest to be fully Python.

We're no longer using run-ingest.sh so it should be removed:

• scripts/VXingest_utilities/run-ingest.sh

While I'm at it, I'm curious if the below files can be removed. I've moved everything explicitly used by the test suite to a testdata directory so these files aren't being called by any code at the moment. I believe the *.n1ql files are safe to remove. The *.yaml files may be examples of data documents though. I also noticed a number of NetCDF files in tests/vxingest/netcdf_to_cb that I'm assuming are out of date and can be cleaned up.

• tests/vxingest/builder_common/*.n1ql
• tests/vxingest/ctc_to_cb/*.yaml
• tests/vxingest/grib2_to_cb/*{.yaml,.xml}
• tests/vxingest/netcdf_to_cb/{2021*,*.yaml}
• tests/vxingest/partial_sums_to_cb/*{.n1ql,.yaml}
