    This seems like a lot of boilerplate that we could abstract using a base 
testing class for ResourceManager tests.

> The {{ResourceManager}} currently does not contain a {{FatalErrorHandler}}. 
> In order to harmonize the fatal error handling across all components, we 
> should introduce a {{FatalErrorHandler}}, which handles fatal errors. 
> Additionally, we should also give a {{MetricRegistry}} to the 
> {{ResourceManager}} so that it can report metrics.
