can you make this private?

[hbos_chromium, 2016/03/08 15:02:10]

This has been updated to be the implementation of the public interface. It shall
not be private because it could be called by webrtc in another context.

       rtc::KeyParams key_params,
+      rtc::Optional<uint64_t> expires_ms,
       const rtc::scoped_refptr<webrtc::DtlsIdentityRequestObserver>& observer)
           override;

[hbos_chromium, 2016/03/04 09:26:31]

The webrtc interface is updating to take |expires_ms|, after this CL the old
version will be removed.

During this transition period both versions exists with default implementation
to call the other implementation, so that only one has to be implemented.
