Description

Regression bug perhaps? Relates to #96

AzureWebJobsStorage keeps getting appended to flex app settings. I have the following set in my TF:

function_app_uses_fc1 = true
storage_account_name                    = "myacct"
  storage_user_assigned_identity_id       ="<uid>"
  storage_uses_managed_identity           =  true
  storage_container_type                  = "blobContainer"
  storage_container_endpoint              = "<endpoint>"
  storage_authentication_type             ="UserAssignedIdentity"

After apply, appsettings get AzureWebJobsStorage and AzureWebJobsStorage__accountName set...

Seems having AzureWebJobsStorage is causing lots of auth errors to backend storage account.

Edit: AzureWebJobsStorage__accountName doesnt get added, has to be added via terraform app settings variable.

Edit2: This is related to bug in the AzureRM provider, refer to hashicorp/terraform-provider-azurerm#29693
