The extension does not work with the 'host' :
Invalid config for [apache_kafka]: [host] is an invalid option for [apache_kafka]. Check: apache_kafka->apache_kafka->host. (See /home/joris/.homeassistant/configuration.yaml, line 18). Please check the docs at https://www.home-assistant.io/integrations/apache_kafka.
Looking at the code it should be 'ip_address'. Tested and works.
As this is my first PR, maybe a better solution would be to change the code to use host instead of ip_address. I could not find any documentation about this and this fix is less errorprone than changing the code.
