> A new kind of module that does *not* receive any callbacks but simply coexists with its parent process. 
> h4.Motivation and Use Cases
> We want to add customized and experimental capabilities that concern the life time of Mesos components without protruding into Mesos source code and without creating new build process dependencies for everybody.
> Example use cases:
> 1. An anonymous module that gathers fail-over incidents and reports summaries thereof to a remote data sink.
> 2. A slave module that observes host computer metrics and correlates these with task activity. This can be used to find resources leaks and to prevent, respectively guide, oversubscription.
> 3. Upgrades and provisioning that require shutdown and restart.
> h4.Module Classification
> Unlike other named modules, an anonymous module does not directly replace or provide essential Mesos functionality (such as an Isolator module does). Unlike a decorator module it does not directly add or inject data into Mesos core either.
