ntopng: updated to 4.0

ntopng 4.0:

Breakthroughs

* Plugins engine to tap into flows, hosts and other network elements
* Migration to Bootstrap 4 and Font Awesome 5 for a renewed ntopng look-and-feel with light and dark themes
* Processes and containers monitoring thanks to the eBPF integration via libebpfflow https://github.com/ntop/libebpfflow
* Active monitoring of hosts ICMP/ICMPv6/HTTP/HTTPS Round Trip Times (RTT)

New features
* X.509 client certificate authentication
* ERSPAN transparent ethernet bridging
* Webhook export module for exporting alarms
* Identifications of the hosts in broadcast domain
* Category Lists editor to manage ip/domain lists
* Handling of PEN fields from nProbe
* Added anomalous flows to the looking glass
* Visibility of ICMP port-unreachable flows IPv4
* TCP states filtering (est., connecting, closed and rst)
* Ability to serialize local hosts in the broadcast domain via MAC address
* Japanese, portugese/brazilian localization
* Added process memory, cpu load, InfluxDB, Redis status pages and charts
* Implement ntopng Plugins, self contained modules to extend the ntopng functionalities
* Implement ZMQ/Suricata companion interface
* SSL traffic analysis and alerts via JA3 fingerprint, unsafe ciphers detection
* SSH traffic analysis and alerts via HASSH fingerprint
* Host traffic profile generation via the (MUD) Manufacturer Usage Descriptor
* Experimental Prometheus timeseries export
* Introduce the System interface to manage system wide settings and status
* Read events from Suricata and generate alerts
* SNMP network topology visualization
* Automatic ntopng update check and upgrade
* Calculate host anomaly score and trigger alerts when it exceeds a threshold
* Add ability to extract timeseries data with a click
* Initial Marketplace droplet using Fabric
* Alerts on duplex status change on SNMP interface

Improvements
* View interfaces are now optimized for big networks and use less memory
* Systemd macros are now used to start/restart the ntopng services
* Handles n2disk traffic extractions from recording processes non managed by ntopng
* Interface in/out now available also for non PF_RING interfaces (read from /proc)
* Automatic InfluxDB rollup support
* MDNS discovery improvements
* Rework of the alerts engine and api for efficient engaged alerts triggering
* Faster ZMQ communication to nProbe thanks to the implementation of a binary TLV format
* Stats update for ZMQ interfaces is now based on the idle/active flows timeout
* Timeseries export improvements via queues, detect if InfluxDB is down and stop the export
* Implemented reusable Lua engine to reduce the overhead of periodic scripts
* Improve Lua error handling
* Exclude certain categories from Elephant/Long lived flows alerts

nEdge
* Ability to set up port forwarding
* Support for Ubuntu 18.04
* Fix users and other prefs deleted during nEdge data reset
* Japanese localization
* Block unsupported L3 protocols (currently only ARP and IPv4 are supported)
* DNS mapping port to avoid conflicts with system programs

Fixes
* Fixed export to mysql on shutdown in case of Pcap file in community mode
* Fixed failing SYN-scan detection
* Fixed ZMQ decompression errors with large templates
* Fixed possible XSS in login.lua referer param and `runtime.lua`
* Update geolocation due to changes in the library usage policy
* Fixes to support browsers dark mode
* Option `--zmq-encryption-key <pub key>` can be used with `-I <endpoint>` to encrypt data hi hierarchical mode
* Fixed nIndex missing data while performing some queries and throughput calculation
