_get_arc_endpoint references wrong path for azcmagent/bin

[msalwen]

The line linked below checks for the existence of /var/opt/azcmagent/bin/himds. On our Arc servers (and probably others) the himds executable is located at /opt/azcmagent/bin/himds. This failure requires manually setting the required env variables to bypass this statement or creating a symlink from /opt/azcmagent/bin to /var/opt/azcmagent/bin.

sys.platform == "linux" and os.path.exists("/var/opt/azcmagent/bin/himds")

Hi, @msalwen , I just noticed that your alias happens to have a prefix msal which is also the acronym MSAL of MicroSoft Authentication Library. :-)

Now we have a beta release with the bugfix for the issue you reported. Would you please install it by pip install -i https://test.pypi.org/simple/ msal and tell us whether it can solve the issue? Thanks!

@rayluo I have checked the beta and it works as intended. Alignment bet my alias and package name is completely coincidental. Microsoft and I happen to share initials. 😄

@jiasli I'm not sure whether you are involved with the Python packages supporting azure-cli as well as the base product, but not surprisingly, installing the msal beta alongside azure-cli-core raised a complaint from the latter about a version mismatch. I hope that a new release of azure-cli-core will follow the updated msal as soon as possible.

Once MSAL releases a new version that includes #763. Azure CLI will adopt it in Azure/azure-cli#30267.
