upload to Azure storage broken due to azure-cli bug

Azure/azure-cli#30635
When uploading to an azure storage bucket, azure-cli will dynamically download a utility called azcopy to actually do it. However, as described in Azure/azure-cli#30635, azure-cli had a hard-coded download URL for azcopy, which has been deprecated and now removed (by Azure lol), so the download fails.

This make the upload fail, unless you already have azcopy downloaded. Existing users probably already have azcopy, which is maybe why we haven't seen this.

azure-cli has pushed a fix but it will only be part of the next release, due on Feb 12. The proposed workaround is to manually download and install the azcopy binary. Which is insane, but they don't seem to see this as a significant issue.

Looks like the following commands can mitigate this on Linux:

curl -L https://aka.ms/downloadazcopy-v10-linux > azcopy.tar.gz
tar xfvz azcopy.tar.gz
cp azcopy_linux_amd64_10.27.1/azcopy ~/.azure/bin
