OCI: Add curl program, to unlock Docker Compose health checks (#419)
## About
The existing healtcheck endpoint http://localhost:8080/health can now be
used without much ado within Docker Compose service definitions, and it
works well.

```yaml
healthcheck:
  test: ["CMD", "curl", "--fail", "http://localhost:8080/health"]
  start_period: 3s
  interval: 1.5s
  retries: 30
  timeout: 30s
```
