Option to configure default network

[markushuber]

Currently the upribox software uses a hardcoded network range for clients:
192.168.55.0/24

In certain cases the default network might overlap with already existing (local/remote) networks.
Rework the affected ansible roles to allow user defined network ranges for clients.

@tobiasdam how complex is to offer an option to change the default network mode?

[tobiasdam]

should not be to complex, will look into it
essentially it is just restarting a bunch of services
