Instead of using a single directory for both the internal data of metricsd and metrics_collector and the shared files (metrics samples log file and the metrics enabled file), we should use separate directory to allow for a finer access control. The new structure will be: * /data/misc/metrics for the files accessible to all daemons reporting metrics, metricsd and metrics_collector. * /data/misc/metricsd for the private files of metricsd. * /data/misc/metrics_collector for the private files of metrics_collector. Bug: 25886951 Test: Unit tests. Test: Manual: metricsd and metrics_collector run without errors. Change-Id: I006d19f45f5f419d2b08744126c2e2a0b899c9fa
