Support azurerm version >= 1.34

[chenlin07]

The current version constraint on azurerm, ~> 1.22, will automatically upgrade to the latest minor release of azurerm 1.x.

When we try to use this repo with azurerm 1.34, we get an error:

Error: Error applying plan:

1 error occurred:
	* module.ops_manager.azurerm_image.ops_manager_image: Resource 'azurerm_storage_blob.ops_manager_image' does not have attribute 'url' for variable 'azurerm_storage_blob.ops_manager_image.url'

Ang then we lock azurerm version to 1.33.0, it works.
