New script to get latest conda artifact from a given repo PR

[harrism]

I found myself creating a bunch of PRs to test downstream affects of an RMM PR on various RAPIDS repos. Each of these required a lot of boiler plate like the following to compute the path to a CI artifact from RMM and other dependent PRs (e.g. cuML depends on RMM and RAFT and CUDF).

REPO="rmm"
PR_NUMBER="1095"
COMMIT=$(git ls-remote https://github.com/rapidsai/${REPO}.git refs/heads/pull-request/${PR_NUMBER} | cut -c1-7)
RAPIDS_CUDA_MAJOR="${RAPIDS_CUDA_VERSION%%.*}"
PYTHON_MINOR_VERSION=$(python --version | sed -E 's/Python [0-9]+\.([0-9]+)\.[0-9]+/\1/g')
LIBRMM_CHANNEL=$(rapids-get-artifact ci/${REPO}/pull-request/${PR_NUMBER}/${COMMIT}/rmm_conda_cpp_cuda${RAPIDS_CUDA_MAJOR}_$(arch).tar.gz)
RMM_CHANNEL=$(rapids-get-artifact ci/${REPO}/pull-request/${PR_NUMBER}/${COMMIT}/rmm_conda_python_cuda${RAPIDS_CUDA_MAJOR}_3${PYTHON_MINOR_VERSION}_$(arch).tar.gz)

This PR adds a new gha-tools script to eliminate a lot of this boilerplate. Now you can do like this:

LIBRMM_CHANNEL=$(rapids-get-pr-conda-artifact rmm 1095 cpp)
RMM_CHANNEL=$(rapids-get-pr-conda-artifact rmm 1095 python)
LIBCUDF_CHANNEL=$(rapids-get-pr-conda-artifact cudf 14365 cpp)
CUDF_CHANNEL=$(rapids-get-pr-conda-artifact cudf 14365 python)

Can someone /ok to test this?

blocking merge while I leave some feedback

The feedback I would've left would've touched the entire file. So I opted to just push a commit instead. Hope you don't mind Mark.

The commit I pushed consists of the following changes:

• Uses rapids-package-name to compute the package name
• Uses a case statement instead if if/elif for consistency with the other scripts in this repository
• Switch the git command to use the gh CLI instead (it's a bit less verbose)

Thanks @ajschmidt8!
