 * Initialize our DependencyManager Runtime service.
 *
 * We depend on the OSGi LogService, and we track all started bundles which do have a
 * "DependencyManager-Component" Manifest header.
 * If the "dm.runtime.log=true" or "dm.runtime.packageAdmin=true" parameter is configured in the Felix config.properties
 * then we'll use a required/temporal service dependency over the respective service.
 * These temporal dependencies avoid us to be restarted if the respective service is temporarily
 * unavailable (that is: when the service is updating).
 * if the "dm.runtime.log" or "dm.runtime.packageAdmin" is not configured or it it is set to false, then we'll use
 * an optional dependency over the respective service, in order to use a NullObject in case
 * the service is not available.
