Migrate to SettingsStatsLog from StatsLog

As part of statsd becoming a Mainline module in R, autogenerated
StatsLog.write() calls are going away and replaced by *StatsLog.java
that is autogenerated for each module.
This CL adds autogenerated SettingsStatsLog and replaces usages
of StatsLog with SettingsStatsLog.
