Added support for non-Public cloud in Azure App Service

[ShilpiRach]

Description

Added the support to derive App Service DNS Suffix from Cloud name. It adds a new optional parameter to AddAzureAppServiceEnvironment method (with Azure public cloud as the default).

The intent is to remove the current hardcoding of App Servic endpoint to https:\\<app service name>.azurewebsites.net irrespective of cloud.
