Detailed Description

A dual-stage boostrap mechanism is used to ensure an orderly startup of the ApplicationMgr.

If this function is called before the singleton ApplicationMgr instance exists, a BootstrapAppMgr singleton instance is created. This responds to any subsequent requests for services by returning StatusCode::FAILURE, unless the ApplicationMgr singleton instance has been created in the interim. In this case, the BootstrapAppMgr forwards the request to the ApplicationMgr instance. The motivation for this is to handle static object instances where the constructor attempts to locate services and would otherwise instantiate the ApplicationMgr instance in an unorderly manner. This logic requires that the ApplicationMgr instance is created explicitly.
