Proper support for collection module configuration

After all the previous (failed) workarounds, this PR finally does it right. Each CollectionModule must now specify the TypeURL of its associated service configuration protobuf message (e.g., such as WorkloadSecurityConfig). This is done automatically in autoCreateCollectionModules. This desired type URL is then matched against the stored type URL in the persisted list of service configurations to properly fill the StartCollectingRequest.
