Added metrics history for WV CDM for Android.

Browse Source 
[ Merge of http://go/wvgerrit/171271 ]

There is a need to maintain a short history of metrics from CDMs which
have been deleted.  This CL adds this ability to the Android version
of the WV CDM.  The history cannot yet be maintained for long, as the
WV CDM instance is destroyed if unused.

Further changes are required to the plugin to maintain the history
beyond the life-cycle of the CDM instance, and to properly format
its output.
