docker: add mqtt vars to dockerStart.sh

[xaviml]

Adds MQTT plugin with the environment variables for the namespace, host, user, and password to the dockerStart.sh file.

Note that this adds the plugin only if the variables are present, so this PR does not break the current functionality.

After running:

docker run --rm \
-e DASH_URL=http://127.0.0.1:5050 \
-e HA_URL="http://xxx.xxx.x.xxx:8123" \
-e TOKEN="MY_HA_TOKEN" \
-e MQTT_NAMESPACE=mqtt \
-e MQTT_CLIENT_HOST=xxx.xxx.x.xxx \
-e MQTT_CLIENT_USER=xxxx \
-e MQTT_CLIENT_PASSWORD=xxxx \
appdaemon
