Add IGsiService::suggestScratchSize()

DSU installation service could call this method to get a suggested
scratch partition size, if the DSU guest system would need overlayFS
(remount) feature. This size is just a suggestion, and is not guaranteed
to work. The caller (framework) should still check if the DSU scratch
partition is allocated successfully. The scratch partition allocation
could fail if the suggested size is larger than available free space.
