Harmonises service.yml file usage of quote marks around port mappings

The [Docker Compose file reference](https://docs.docker.com/compose/compose-file/#ports)
says:

> When mapping ports in the HOST:CONTAINER format, you may experience
erroneous results when using a container port lower than 60,
because YAML parses numbers in the format xx:yy as a base-60 value.
For this reason, we recommend always explicitly specifying your port
mappings as strings.

This PR adopts the recommendation on all `service.yml` files in the
`.templates` directory. That way, IOTstack uses who work by copying
an existing example will be less likely to strike this problem should
they need to specify a container port less than 60.

I also removed some extraneous blank lines at the ends of `service.yml`
files that were causing sub-optimal layout in `docker-compose.yml`.
