add a new eventscript : 99.routing that is used to add static routes to

interfaces when they are activated (an ip address is added during
takeip)

(This used to be ctdb commit d9779c310e98c9d4eab71a8d1705849ac90deb10)

+# script to add entries to the routing table after we have performed a
+# take ip event
+# (when we do a "releaseip" event and remove an ip address from an interface
+#  the kernel might automatically remove associated entries from
+#  the routing table. This is where we add them back)
+#
+# Routes to add are defined in /etc/ctdb/static-routes.
+# Syntax is :
