[Bug] Defaults configuration set from environment variables are not honored

[ggirard07]

Describe the bug
Defaults configurations defined as environment variables are not honored when invoking devops commands

To Reproduce

$ az --version
azure-cli                         2.22.1
core                              2.22.1
telemetry                          1.0.6
Extensions:
azure-devops                      0.18.0

Steps to reproduce the behavior:

1. $ az login
2. $ export AZURE_DEVOPS_EXT_DEFAULTS_ORGANIZATION=https://dev.azure.com/myorg
3. $ az repos list --project myproject --detect false
4. See error about missing organization information in command invokation

Expected behavior
Organization should be picked-up from defaults configuration set as environment variable

Additional context
I confirmed the configuration is properly set as env variables with following commands ran from same shell:

$ az devops configure -l

Use git alias = No

Environment variables:
AZURE_DEVOPS_EXT_DEFAULTS_ORGANIZATION

and

$ python -c "import os; print(os.environ['AZURE_DEVOPS_EXT_DEFAULTS_ORGANIZATION'])"
https://dev.azure.com/myorg

The requested thing is not supported by design.
Also, you can use the following link to configure default organization and project

https://docs.microsoft.com/en-us/cli/azure/devops?view=azure-cli-latest#az_devops_configure

[ggirard07]

As this is used on an Azure DevOps build agent, running concurrent jobs, I cannot use az devops configure as this will impact the concurrent jobs. Settings the environment variables in the job context, as support per Azure CLI, seems to be the only solution in this case!

I am not sure I understand the "as designed" for DevOps CLI extension in this case, as it does NOT match the default Azure CLI behavior...
