FEATURE REQUEST: Add client_id to the MQTT connection

[51av0sh]

Would it be possible to add client_id variable to the MQTT connection? I needed to troubleshoot some unrelated issues to docker-wyze-bridge and while doing so I noticed that docker-wyze-bridge uses a random client id on every connection, which seems to be every 20 seconds. I'm not a coder but after feeding the code to chatgpt it seems to be an easy fix, I'm just not sure if this 2 line change would break anything else.

Existing code:

`def mqtt_sub_topic(m_topics: list, callback) -> Optional[paho.mqtt.client.Client]:
"""Connect to mqtt and return the client."""

def on_connect(client, *_):
    """Callback for when the client receives a CONNACK response from the server."""
    client.publish(f"{MQTT_TOPIC}/state", "online", retain=True)
    for topic in m_topics:
        # Clear Retain Flag
        client.publish(f"{MQTT_TOPIC}/{topic}", retain=True)
        client.subscribe(f"{MQTT_TOPIC}/{topic}")

client = paho.mqtt.client.Client(paho.mqtt.client.CallbackAPIVersion.VERSION2)

client.username_pw_set(MQTT_USER, MQTT_PASS or None)
client.user_data_set(callback)
client.on_connect = on_connect
client.will_set(f"{MQTT_TOPIC}/state", payload="offline", qos=1, retain=True)
client.connect(MQTT_HOST, int(MQTT_PORT or 1883), 30)
client.loop_start()

return client`

# Add a custom client_id here
client_id = "YourUniqueClientID"

Apologies for the bad formatting. I've tried several times and can't get the code block right.
