Drop cherrypy.lib.http

[webknjaz]

@jaraco look what I've found: https://github.com/cherrypy/cherrypy/blob/b6e15ab4624947bea8cbc03cc40cf26016408ae5/cherrypy/lib/http.py

I think we should delete it, but first ensure the codebase doesn't rely on this module

cherrypy/cherrypy/lib/__init__.py

Lines 3 to 4 in b6e15ab

	# Deprecated in CherryPy 3.2 -- remove in CherryPy 3.3
	from cherrypy.lib.reprconf import unrepr, modules, attributes

Here's another one. Does the deprecation comment describe only import line or the whole module?
