Since all Quagga daemons are configured from a consolidated
location (the 'zebra' service), there is nothing left to do
for a dedicated service such as 'vtysh'. This patch removes
the service, along with all references to it from the rest
of the source tree (sample *.imn files, examples, etc.)

note that due to the usage of the 'server' global, it will not work to add a
Session.add_to_server() or core.misc.utils.add_to_server() function
