The key difference between these groups is not that one needs a jump
host and the other does not, but that all hosts of one group run on
machines located in the Netz39 rooms in Magdeburg, while the other group
contains only hosts hosted anywhere in the public internet. We'll need
this distinction for more things than SSH in the future, e.g. PR !132.
(This is also better, because technically there could be a third group
requiring a jump host which is not ssh.n39.eu … 😉 )

The previous configuration was copied over from helium.n39.eu for
prosody v0.9 and did only work more or less by accident. The new
configuration was done based on the upstream example configuration.
Some modules we used for 0.9 were replaced, some are not necessary
anymore, some modules are new for 0.11. The list was reviewed carefully
on a test host, and proved to work for several months there.
The VirtualHost 'localhost' is kept, but moved from a separate
configuration file to the main configuration, because it's only one line
and it's part of the example config anyways.
Apparently Mosquitto had some breaking changes in the configuration,
so we need to add some values to the new version.
This only became visible after the DNS change in our Router. This fix
has been tested and is working.
