CLEANUP: examples: remove obsolete configuration file samples
This removes the obsolete CTTPROXY configuration, the tarpit example,
and the pre-content switching example involving 3 layers and cookie
rewriting to emulate the use_backend feature... (9 years old).

-# This configuration can be used as an example of how URL-switching may be

-#
-# Right now (version 1.2), haproxy can only select a server based on the cookie
-# provided by the client. While this may sound limitated, it is yet possible to
-# combine this feature to rewrites to provide full URL-switching capabilities.
-#
-# For this, we have to chain 3 levels :
-# - front-end : will match the expected URIs and assign a cookie accordingly ;
-# it uses regexps and could match on anything else (Host:,
-# cookies, ...)
-# - switch : will select a back-end depending on the cookie above
-# - back-ends : will perform the load balancing between multiple servers for
-# the same group. Note that this level can be omitted if there
-# is only one server for each backend.
-#
-# Logging is performed at the lower level (back-ends) so that local server
-# problems can be identified quickly with the timers. The client's IP is
-# propagated in the X-Forwarded-For: header.
