Issue determining storageAccount share endpoint.

Mahara quick start template (https://github.com/Azure/azure-quickstart-templates/pull/4657)

There doesn't seem to be an endpoint property in the template API (https://docs.microsoft.com/en-us/azure/templates/microsoft.storage/storageaccounts) and it seems the ARM templates cannot be used to create a share (https://social.msdn.microsoft.com/Forums/vstudio/en-US/dbd76a04-9964-4ccc-8b0b-a9a5c6664de3/need-to-create-azure-files-share-with-arm-template-how?forum=azureapimgmt), the share is actually created in the helper script (scripts/helper_functions.sh:14). I also note that the quick start templates linked via the StorageAccount API page has hard coded endpoint suffix (https://github.com/Azure/azure-quickstart-templates/blob/master/centos-2nics-lb-cluster/azuredeploy.json:451 and https://github.com/Azure/azure-quickstart-templates/blob/master/201-2-vms-loadbalancer-lbrules/azuredeploy.json:330, is there some API call that can be used at all to ascertain the storage end point? Aside from this, all of the other items noted have been updated.

Start with scripts/helper_functions.sh:14 and the endpoint references in centos-2nics-lb-cluster/azuredeploy.json:451 and 201-2-vms-loadbalancer-lbrules/azuredeploy.json:330. Compare these with the StorageAccount template API documentation and the linked Mahara pull request. Done means identifying a supported way to determine the share endpoint or documenting that none exists and updating the affected guidance.
