Wizard commands are still broken for Azure Government. Working to resolve.

Currently, Logic Apps and Integration Accounts are displaying in their respective views. The .json ARM templates can be opened, edited and saved. However they can not be opened in the visual editor (see below).

Still trying to narrow down the issue with the ResourceGroupListStep implementation. I've extended ResourceGroupListStep to override the built in getResourceGroups() so baseUri can be passed in but still running into same "Subscription Id {x} not found" error when trying to create a Logic App or Integration Account within VSCode.

The createAzureClient() which is used by getResourceGroups() seems to account for the baseUri, however during compile it seemed like the baseUri parameter was being dropped and not passed into the ResourceManagementClient().

Still investigating. Please let me know if we want to close this PR and re-open when work is completed.

Thanks
