  - netconf-pnp-simulator: fix sysrepod crash on TLS reconfig

    The crash was caused by:
    - the '--permanent' option while updating the ietf-keystore by
      sysrepocfg
    - missing some Yang modules on sysrepo installation

    Other changes:

    1. Added TLS integration tests, including reconfiguration
    2. reconfigure-*.sh are now synchronous, only returnig after restart is
       completed
