medsrv/medcli: Remove prototypical medsrv web application and plugins

This was from a student project that has never been developed further.
And similar to the manager web application it lacks all sorts of modern
standards.  So just remove it and the two plugins it relied on.

The test scenario is renamed to avoid confusion (neither of the two
p2pnat scenarios uses medsrv/medcli).
