      usage:
      ./importnordvpn.sh [-u <"username">   -p <"password">][-h][-d <"directory"> || -g][-c]
            -u username (is mail ) it must be in qoutes " "

            -d patch to direcotory  ovpn files arguments not required
                you can run script in direcotry white space in patch
                not working.
            -g Get configs from network.
            -c clean DANGER, roemove all connection type vpn from nmcli
            -t Temporary use this for test, added configuration
                disaper after restart NetworkManager (nmcli)
            -h it is this information
            -r Test function for fast add servers , all operations
                works on ram disk and NetwormManager is restarted every 30 new added configs
      examples:
            ./importnordvpn -u "myemail@exampl.com" -p "P44SSwoRd"
          or
            ./importnordvpn -u "myemail@exampl.com" -p "P44SSwoRd" -d Download/configs/
          Get configuration from nordvpn.com
            ./importnordvpn -u "myemail@exampl.com" -p "P44SSwoRd" -d
          if you want clean configuration
             ./importnordvpn -c
          clean configuration (remove all vpns from nmcli ). and load new
            ./importnordvpn -c -u "myemail@exampl.com" -p "P44SSwoRd" -d Download/configs/
