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
# implemented with current haproxy versions.
#
# 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.
