1.9.8 ARM example suggests same port for control agent and HA+MT peers, which will result in port conflict

Log entry: 2021-07-21 00:13:43.385 ERROR [kea-dhcp4.packets/12631.140012750506176] DHCP4_PACKET_PROCESS_STD_EXCEPTION exception occurred during packet processing: CmdHttpListener::run failed:unable to setup TCP acceptor for listening to the incoming HTTP requests: bind: Address already in use

Examples:

From ARM 7.2:

"Control-agent": {
    "http-host": "10.20.30.40",
    "http-port": 8000,

From ARM 16.15.8:

"peers": [{
    "name": "server1",
    "url": "http://192.168.56.33:8000/",

The IPs are different in the text, obviously, but if these are run on the same server using the same IP address, then there will be a port conflict when http-dedicated-listener tries to bind to port 8000.
