Tianjie Xu 3bbb20f557 Add a singleton CacheLocation to replace the hard coded locations ... This class allows us to set the following locations dynamically: cache_temp_source, last_command_file, stash_directory_base. In the updater's main function, we reset the values of these variables to their default locations in /cache; while we can set them to temp files in unit tests or host simulation. Test: unit tests pass Change-Id: I528652650caa41373617ab055d41b1f1a4ec0f87		2018-02-28 11:19:11 -08:00
