DO NOT MERGE ANYWHERE: UsageStatsService: Fix app idle issue at rollover time App Idle queries are very frequent and so they only check in memory stats. However, in memory stats can be missing some entries, especially after a rollover, but also due to a larger bug fixed in master (too risky to take now). The fix is to do a deep query (reading older files from disk) and maintain a parallel cache of stats for app idle. That way the rolling window of data required to serve app idle queries stays in memory. Bug:26355386 Change-Id: I6a29bbc25214f6a3c2f24c8c079936e66f99e42e
