/**
* InheritableThread is a scope that operates like
* {@link athenz.shade.zts.athenz.shade.zts.org.glassfish.hk2.api.PerThread} scope, except with the caveat that
* InheritableThread scoped services provide inheritance of values from parent
* thread to child thread. The lifecycle of the service is determined by the
* thread it is on. On a single thread only one of the service will be created
* and the service will be inherited by its child threads, but a new service
* will be created for each new non-child threads.
*
* The InheritableThread scope is not automatically handled by a new
* ServiceLocator. In order to enable the InheritableThread scope * the user can
* either add an implementation of {@link Context} which handles it or it can
* use the
* {@link athenz.shade.zts.athenz.shade.zts.org.glassfish.hk2.utilities.ServiceLocatorUtilities#enableInheritableThreadScope}
* method.
