[YARN-4552] NM ResourceLocalizationService should check and initialize local filecache dir (and log dir) even if NM recover is enabled.

Description

In some cases, user are cleanup localized file cache for debugging/trouble shooting purpose during NM down time. However, after bring back NM (with recovery enabled), the job submission could be failed for exception like below:

Diagnostics: java.io.FileNotFoundException: File /disk/12/yarn/local/filecache does not exist.

This is due to we only create filecache dir when recover is not enabled during ResourceLocalizationService get initialized/started.
