[ Merge of http://go/wvgerrit/111903 ]
CDM metrics has been updated to include the DRM key type. The CDM
session records the key type when the wrapped DRM key is successfully
loaded into an OEMCrypto session.
Now that the API refers to a general DRM key rather than an RSA key,
the timer metric for loading the DRM key has been renamed on the client
to reflect this.
Test: Metric unit tests
