support cpp wheels in 'rapids-wheels-anaconda'

[jameslamb]

Contributes to rapidsai/build-planning#44.

Proposes removing hardcoding of _python_ in the search for artifact names performed by rapids-wheels-anaconda, to enable uploading of C++ wheels (which will have _cpp_ in artifact names).

Notes for Reviewers

I think this would be safe to merge right now... it should be totally backwards-compatible because it defaults to _python_ when a pkg_type isn't supplied.

To see how the entire S3 object key is computed, also see this:

gha-tools/tools/rapids-s3-path

Lines 8 to 15 in 4c878b8

LGTM! We have a test confirming that this works.

LGTM.

Do you think it's worth adding a case statement to ensure PKG_TYPE is cpp or python?

Similar to what we do here:

gha-tools/tools/rapids-download-conda-from-s3

Lines 11 to 20 in 4c878b8

	case "${pkg_type}" in
	cpp)
	;&
	python)
	;;
	*)
	rapids-echo-stderr 'Pass "cpp" or "python" as an argument.'
	exit 1
	;;
	esac

Great suggestion, thanks @ajschmidt8. Just pushed ad0e188 adding that.

Tested it by adding one of these after the case block

echo "--- ${PKG_TYPE}"
exit 6

and then a few different combinations

# fails with this error
PATH="${PWD}/tools:${PATH}" rapids-wheels-anaconda beepboop cpp2

# succeeds
PATH="${PWD}/tools:${PATH}" rapids-wheels-anaconda beepboop cpp

# succeeds
PATH="${PWD}/tools:${PATH}" rapids-wheels-anaconda beepboop python

# succeeds, defaults to 'python'
PATH="${PWD}/tools:${PATH}" rapids-wheels-anaconda beepboop

merge away!
