Faucet

* Enable global routing (if one router only is defined, and dp/global_vlan is set to an unused VID, router will use that VID for all routed VLANs so that FIB scales linearly)
* Fix incorrect use of class attributes that could cause objects (like ports) to have incorrectly entangled attributes (like port up status)
* Fix LACP port status Prometheus variable.
* Fix sending DEC_TTL action for TFM switches that support it.

* More extensive testing for looped packets from DP.
* Don't do any link local routing at all
* Fix lacp_port_state Prometheus variable
* Skip port ACL table if not present
* Fix hosts not being learned on stack root after move
* Better logging for port state transitions

* TFM JSON config files have been removed - all TFM features are automatically generated, except for table sizes, which can be configured like so:


dps:
mytfmdp:
table_sizes:
port_acl: 1024
... etc ...


* eth_dst is now an exact match table (ACL tables can be exact match, in the future other tables will be too)
* Ryu 4.27
* Explicitly drop ECTP (eth type 0x9000)
* Fix receiving load balanced MAC from LACP bundle.
* Fix allow: 1 should work with output: ACL actions.
* Fix do not inter-VLAN route link local networks.
* Fix port ACL table could unnecessarily require VLAN VID match.

* Automatically generate OF apply_actions for TFM switches (update of JSON TFM files is required - JSON files will be removed once table sizing has been automated)

* Dynamically generate matches for TFM switches, for non-ACL tables. Future releases will remove the switch specific JSON files.
* Fix fuzzers (remove unneeded python2)
* Faster stack learning for edge switches
* Avoid unnecessary switch config on cold start on reconfiguration

* Fix VLAN changes on restart not handled correctly when all ports change
* Fix deletes for tables which are not used
* Fix star topology for stacking (looped packets)
* Fix clib tests not running for hardware
* Remove Ryu for python2 (not needed for some time)
