Publish MLX API Client to PyPI about mlx

[ckadner]

@romeokienzler -- I updated the api/client/README.md with instructions to install the MLX API client directly from GitHub

pip install "git+https://github.com/machine-learning-exchange/mlx.git@main#egg=mlx-client&subdirectory=api/client"

[ckadner]

@romeokienzler -- here are a few commands to test the pip install

# create a temporary directory
mkdir temp
cd temp

# create Python virtual environment
python3 -m venv .venv_mlx_client

# activate the virtual environment
source .venv_mlx_client/bin/activate

# install the MLX client
pip install "git+https://github.com/machine-learning-exchange/mlx.git@main#egg=mlx-client&subdirectory=api/client"

# show all the installed Python packages (should include "mlx-client      0.1.27-pipeline-namespace")
pip list

# run a simple Python command to show the mlx-client install location
python3 -c "import swagger_client; print('\nMLX Client is installed here: ' + swagger_client.__file__ + '\n')"

... and with output:

$ mkdir temp

$ cd temp

$ python3 -m venv .venv_mlx_client

$ source .venv_mlx_client/bin/activate

(.venv_mlx_client) $ pip install "git+https://github.com/machine-learning-exchange/mlx.git@main#egg=mlx-client&subdirectory=api/client"

@ptitzler -- let me know if/when you will need to use a MLX API Client SDK for pulling MLX assets into Elyra. I think using a Python SDK rather than using the REST API endpoints would be preferable.

[ckadner]

There is some clean-up work to be done before we can publish the MLX API Client to PyPI.

[ptitzler]

No rush. The poc surfaced some design issues that we need to tackle first before we can properly support reading from remote catalogs.
