Wondering whether we can merge these two by putting the ProvisionFether in the
MediaClientAndroid interface.

For example, add a factory function in MediaClientAndroid:

scoped_ptr<ProvisionFetcher> CreateProvisionFetcher();

Or probably just add a call in MediaClientAndroid:

RequestProvision(const std::string& default_url,
                 const std::string& request_data,
                 ResponseCallback cb);

MediaClientAndroid now has the method CreateDefaultFetcher() which uses the last
active user context and is designed for the Chrome's ResetCredentials. The
fetcher for the second path (on-demand provisioning in MediaDrmBridge) happens
completely within content/.
