All of this stuff should be part of a data reduction proxy initialization API
that's used by IOThread and ProfileIOData. This API should be compatible with
Android Webview's use.

We are creating instances of 3 different classes here: DataReductionProxyParam,
DataReductionProxyAuthRequestHandler, and DataReductionProxyUsageStats. They
should probably be bundled within a single class. Will leave this as is for now
to keep this cl small.
