1. let logs be written to statsd directly like all other stats logs.
+ stats log should not write to logd anymore(b/78239479)
2. fixed the log format
+ need to embed the elapsed real time in the log
3. fixed the log context reuse problem
+reset the log context buffer and internal state before reuse
