Fix healthcheck issue on Docker (#72)

### What was the problem?

This PR resolves #LISK-1129

### How was it solved?

- [x] Update healthcheck command on the Docker container
- [x] Set the API server host/port within the containers via the env
file build script
- [x] Update default API server host to be `0.0.0.0`
- [x] Update docker dev script to build image from local

### How was it tested?

Start the containers locally with the docker dev scripts
Run: `curl --fail https://localhost:3000/healthz` and check container
health with `docker ps`

docker-compose.yml
