Define simple healthchecks for simulators

- currently containers are healthy if they have successfully started
their Http servers thus simple endpoint at /healthcheck is sufficient
- to enable docker healthcheck we need to add `curl` to docker images
- http_proxy needs to be provided for docker to be able to build images
behind proxy

Closes ONAP-695
