Description

subscription_id is a required provider configuration value, however, when using az-cli auth it is provided implicitly. This PR updates the provider to allow for this condition that was unintentionally blocked.

Note: Users must ensure that appropriate auth and configuration is available to the cli user and ensure the use_cli provider property is set to true for this functionality to be functional and operate as expected.

can use_cli parameter be picked up from the ARM_USE_CLI environment variable? The documentation doesn't say if anything but other parameters, like use_msi and use_oidc, can.
