acr-env not pushing to Azure container registry in China

[maxmantz]

Actual behavior
We try to use the acr-env method to push an image to an Azure container registry in China. However, the login defaults to the .well-known auth configuration for the Azure global cloud where the tenant cannot be found:
This is the error message:

error checking push permissions -- make sure you entered the correct tag name, and that you are authenticated correctly, and try again: checking push permission for "{redacted}.azurecr.cn/{redacted}:latest": resolving authorization for {redacted}.azurecr.cn failed: error getting credentials - err: exit status 1, out: `failed to acquire refresh token error refreshing sp token - adal: Refresh request failed.

Expected behavior
We would like to see an option to push to the Azure China cloud instead of the global cloud.

To Reproduce
Steps to reproduce the behavior:

1. Setup a container registry in Azure China
2. Configure kaniko with acr-env and environment variables for China cloud
3. See the error message above.
