Save multiple copies of update engine logs Right now we only have one copy of update engine log; and it's overwritten if the device reboots or update engine restarts. This CL save multiple copies of the logs with timestamp in "/data/misc/update_engine_log/". It also implements a function to keep the most recent five logs but delete the old ones. Bug: 72080233 Test: Logs are created with correct permission; and old logs are deleted when update engine starts. Change-Id: I9853546bce879e7fbd6380419a85e01256331247
