Refactor common components in runtime-local and runtime-standalone

Currently, `Runtime-Standalone` depends on `Runtime Local` and `Runtime YARN` on a few classes since it uses the exact same code from those components. Since these components are shared between these runtime components, it would be better to refactor these code inside `reef-common` with appropriate comments for those classes, to manage these shared files and to prevent dependencies between different runtime components.
It is also necessary to find a suitable `RootFolder` name for these commonly used classes, where the results of these runtimes will be saved.
