Faucet

Do not upgrade pip (use system provided version only)

* Ryu 4.24
* Prometheus/Grafana upgrades
* Fix missing eventlet monkeypatch for BGP support
* Docker containers for Gasket (802.1x support) - RADIUS and hostapd
* Fix bad Prometheus default address for Gauge (should listen IPv4/IPv6 all)
* Better default for maximum proactive learn attempts (subnet scan resistance)
* Fix gNMI cert generation
* LLDP org_tlv fields can be bytearray or int

* Enable send barrier after TFM, and send set_config/set_async early.
* Change combinatorial_port_flood default to False (depend on OF spec behavior to not send out input port unless requested with reserved port)
* Add FAUCET for the first time tutorial
* Add notify event for port status at DP connection time

Upgrading to this release may require manual steps, check the [release notes](https://docs.faucet.nz/en/latest/release_notes/1.7.0.html) for more details.

* Package faucet/gauge for debian & ubuntu
* Start using new directories for config and logs
* Fix crash clearing cache on port with permanent_learn: True
* Fix duplicate flow/group adds/deletes
* Fix port mirroring of broadcasts to port
* Increase parsing performance (switch to YAML CLoader)
* Make combinatorial_port_flood configurable, default True but will switch to False in next release for fewer OF rules (L3 not yet supported)
* Add force_port_vlan option in ACL rules to force packet into a different FAUCET VLAN (requires combinatorial_port_flood: False)
* Add port override_output_port: n to force traffic from a port to a static port while still supporting MAC learning
* Disable barriers for OVS (less OF messages, OVS doesn’t use them anyway)

Test base image build can fail, because pip doesn't reliably install setuptools before ryu.
