[Proposal] Docker Healthcheck for ACS on docker-compose

[iohann95]

Good afternoon everyone.
Alfresco already has an endpoint to verify if the application is running ok:

        healthcheck:
          test: "curl -f http://localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/probes/-live-"
          interval: 30s
          timeout: 10s
          retries: 6
          start_period: 10m

On my personal opinion it would be good as this helped me to keep track of the status of my Alfresco instances on my Zabbix.
If the project maintainers agree I can do a pull request to add this to the default yaml.
Thanks.
