Added support for UniFi SmartPower Strip along with DHCP improvements

Improvement(s)

? [UAP] Adds support for the adoption of UniFi SmartPower Strip (Early Access).

✔ ️ [UAP] Improve DHCP compatibility, especially when using third-party or non-UniFi DHCP Servers.

Resolved Issue(s)

✔ ️ [UAP-G2] Fix intermittent broadcast and multicast packet drop on gen2 APs, introduced in 4.3.24. This impacted users with non-UniFi DHCP servers which use broadcast for DHCP, along with IoT devices that rely on multicast for discovery.

Note(s)

? All URLs use HTTPS. This assumes your device/s are running 3.7.56 or later and that the device's date is properly set. Please change URLs to HTTP for the device(s) running earlier firmware or if the date is incorrect (e.g. if the device can't reach an NTP server).

? You may start to see EVT_AP_RestartProc events in the controller log. If you see these, please report if there is anything specific in your setup that triggers the events. The processes restarting is not new, but the reporting of the restarting is, and we are using these reports to clean up these issues.

❗ US-XG-6POE upgrading from 4.0.2 or earlier will take a long time to upgrade. Don't be surprised if your switch is unavailable for 5-10+ minutes as 4.0.3+ also updates the PoE firmware to improve PD compatibility.

? UIS-8-450W upgrading from 4.0.33 and earlier will have their PoE firmware upgraded automatically to improve PD compatibility. That process will take a few minutes. PoE will be unavailable during the upgrade process.

❗ USW-16/24-PoE running 4.0.44 cannot directly upgrade to firmware 4.0.60 or later. Please upgrade to THIS release first via custom upgrade and then you'll be able to upgrade it to firmware 4.0.60+.
