> At present at multiple places user local cache file path and user application file path are getting calculated.
> It is better to expose them as a single static utility method and reuse them everywhere else.
> Locations :
> * ContainerLaunch
> * DefaultContainerExecutor: this already has some methods like this
> * ResourceLocalizationService: getUserCacheFilePath getAppFileCachePath
> * ContainerLocalizer
> * ShuffleHandler.Shuffle
> * TestContainerLocalizer, TestContainerManager, TestDefaultContainerExecutor and TestResourceLocalizationService.
