They are already in slapos stack

- add power_on parameter
- fix amarisoft_version parameter in ue
- fix com address in UE configuration
- add nginx for the websocket

During tests a hostname and port is provided instead
of an URL, so hostname needs to be retrieved

Update gNB configuration to match 2024 Amarisoft

User is still allowed to input a hidden parameter
to change the version

After dropping _force_slapos_node_instance_all tests with parameter propagation
need special treatment:

 * during first waitForInstance it is needed to wait for instance for the
   parameterto be requested to the master
 * during second waitForInstance the parameter is being propagated to other
   instances

This is solved by waitForInstanceWithPropagation

In some cases tests are modyfing in-place partitions (eg. .slapos-resource)
in order to mock some states. Then it's required to force instatiation with
waitForInstanceWithForce.

In other places additional, sometimes conditional, processing is added in
order to account for non forced default processing.

Do not force --all for instance in order to test real instantiation.
