Service compatible Dispatcher configuration.

AEM as a Cloud Service has defined rules which are to be followed while configuring Dispatcher for AEM instances.
Dispatcher Converter reads on-Premise or Adobe Managed Services (AMS) Dispatcher configurations and changes them
to AEM as a Cloud Service compatible dispatcher configurations.`;
