free5GC provided as a sample for CNF on VM does not work

[Naoaki Horie]

We deployed using the free5GC provided as a sample for CNF on VM[1], but it didn't work due to the following issues:

 - Installation of Multus-CNI failed because the file path has changed in git repository of the latest Multus-CNI.
 - Failed to load parameter file of the instantiateVnfRequest due to JSON format error.
 - Failed to connect to the container of free5GC network functions and the OVS bridge interface due to used unmanaged MAC address by the neutron.
 - Failed to establish a session between SMF and UPF due to UPF could not be configured after scale-out operation.
 - SMF does not work properly because SMF and NRF were deployed on different worker nodes.
 - Failed to instantiate VNF operation on VNF due to it was not a proxy environments.
 - kubernetes v1.24.0 or latest is not supported.
 - The free5GC does not work after heal operation because the UPF is not reconfigured and the SMF is not restarted.
