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.
