Comment out the long unused afaik HTTP agent handlers.

As far as I know, this was only used by the IBM Rest modules, much of which has been commented out for a very long time now.  Other similar code uses HTTP or stream handlers instead.
So commenting this out to reduce code complexity and the need to make this facility consistent with the others where it may not be used anyway.
If this facility is actually being used then please notify me or uncomment it if you are core.
