TESTS: move tests/*.cfg to tests/config

These are a collection of test files for a variety of features (old or
more recent). 2 or 3 files were found lying there non-committed and
were moved at the same time. A few deprecated or obsolete keywords were
updated to their recent equivalent. Many of these configurations are
made to trigger different parsing errors so it is normal that plenty
of them fail.

Now the tests directory is cleaner and easier to navigate through.

+# This is a test configuration.
+# It makes use of a farm built from 4 active servers and 4 backup servers,
+# all listenening to different IP addresses on port 80. Health-checks are
+# TCP only on port 81 so that iptables rules permit easy selection of which
+# servers are enabled or disabled. It checks for the file /alive, and disables
+# the server if the response is 404.
+#
+# Create statistics counters this way :
+#
+#   iptables -N http
+#   iptables -A OUTPUT -p tcp --syn --dport 80 -j http
+#   for i in $(seq 1 8); do iptables -A http -d 127.0.0.$i; done
+#   iptables -A http -d 127.0.0.0/24
+#
+# Consult the statistics using iptables this way:
+#
+#   iptables --line-numbers -nxvL http
+#   iptables -Z http
+# 
+# Block individual servers like this :
+#   iptables -I INPUT -p tcp --dport 81 -d 127.0.0.1 -j DROP
+#
+# Enable each server like this :
+#   touch $SRV_ROOT/alive
+#
+# Disable each server like this :
+#   rm -f $SRV_ROOT/alive
+#
