In the spirit of moving URLRequestContext members into
URLRequestJobFactories/ProtocolHandlers I figured it would be good start by
moving out this member of ChromeURLRequestContext.  This should facilitate
Albert's work also.  Want to take a look at this small-ish CL?

LGTM.

If there is other stuff that can be removed at this time (i.e., removing any
static factories that are now expected to be superceded by ProtcolHandlers
anyway, and thereafter removing their related context properties) it's probably
worthwhile in advance of Albert's work too.

Matt, PTAL.

Don't think this is needed any more.
