As mentionned in bug #405 we continue to reference architecture.txt from
places in the doc despite this file not being packaged for many years.
Better drop the reference if it's confusing.

This is an introduction to present HAProxy. The aim is to get rid of the
totally obsolete haproxy-en and haproxy-fr files. This file references
another one which is not there yet and which should cover the remaining
part of these obsolete files, which is how to manage the process. The
format is the same as the other docs so it should integrate seamlessly
to existing docs.
