Exclude the default CDM from metrics history.

Browse Source 
[ Merge of http://go/wvgerrit/173410 ]

The DRM plugin opens and closes many CDMs using the default identifier.
These metrics are not needed when checking the metric history and will
no longer be stored.  Default CDM metrics will continue to appear in
the live metrics list.
