  - netconf-pnp-simulator: convenient TLS and SSH configuration

    - Simple SSH and TLS configuration. Instead of specific Netopeer2
      XML configuration files, the user only needs to provide:
      For SSH: id_XXX.pub
      For TLS: server_key.pem, server_cert.pem, and ca.pem

    - SSH and TLS can be reconfigured at runtime by running
      /opt/bin/reconfigure-ssh.sh and /opt/bin/reconfigure-tls.sh respectively

    - Improved log readability by using zlog (on C applications) and loguru
      for Python

    See the updated documentation under ../docs for more information.
