Installation of ML extension fails with pip error

[jgtellez1]

az feedback auto-generates most of the information requested below, as of CLI version 2.0.62

Describe the bug
When installing the Azure Machine Learning CLI extension, we see this error:
ERROR: An error occurred. Pip failed with status code 1. Use --debug for more information.

Using the debug flag we see an error from cryptography:
error: Can not find Rust compiler
Building wheel for cryptography (PEP 517): finished with status 'error'
ERROR: Failed building wheel for cryptography
and
pip._internal.exceptions.InstallationError: Could not build wheels for cryptography which use PEP 517 and cannot be installed directly

To Reproduce
Create a Dockerfile with these lines:
FROM mcr.microsoft.com/azure-cli
RUN az login
RUN az extension add -n azure-cli-ml

Expected behavior
ML CLI extension installs.

Environment summary
Using base mcr.microsoft.com/azure-cli image.

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc azureml-github.

Yunge Zhu (@yungezz) The issue is happening only when using mcr.microsoft.com/azure-cli docker image. az ml extension installation done on local machine works fine. Looks like an issue with the image.

It's caused by the latest version of cryptography as described in #16858 It's related to whether the underlying platform supports rust.

azure-cli currently pinned cryptography with 'cryptography>=2.3.1,<3.0.0', but azure-ml-cli relies on adal and it depends on cryptography with no version upper bound. When installing the azure-ml-cli extension, it will try to install the latest version of cryptography.

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc Cody (@lostmygithubaccount).

A new patch release whl has been made that should fix this issue. It pins the cryptography package to be compatible:
az extension add -s https://azurecliext.blob.core.windows.net/release/azure_cli_ml-1.22.0.1-py3-none-any.whl -y

This has not yet been released to the general az extension add -n azure-cli-ml yet - we are working on that. In the meantime, you can use the above command instead to get the patch.
