Security: MQTT password logged in plaintext in log
When loggin in to MQTT the password is being redacted. This is fine:
`[8/14/2023, 9:44:31 AM] [Unifi Protect] CloudKeyG2Plus: Connected to MQTT broker: mqtt://user1:REDACTED@192.168.1.99 (topic: unifi/protect).`

However, when disconnecting the password is being logged:
`[8/14/2023, 9:45:31 AM] [Unifi Protect] CloudKeyG2Plus: Disconnected from MQTT broker: mqtt://user1:notmyrealpassword@192.168.1.99.`
