switched port field to a JSONField adds a helper function to display server port mapping in admin launching a container will map the ports appropriately Instead of typing json to map ports we have a widget replaced by such text fields. where one can + button to add or - to remove i.e. [container_port/proto]:[host_port] At first port was an IntegerField. Hence i added a manual migration which is the latest one to get them to be default:port(old value) Signed-off-by: Pratyush Desai <pratyush.desai@liberta.casa>
