Secure myhero-data from direct access

[hpreston]

Currently the myhero-data service is deployed in a mode where it is proxied through traefik. This is unneeded and a security risk. Update the integration of the application to have the "app" and "ernst" leverage consul lookups to find the data service local address and connect directly and not through a public FQDN. Then update the myhero/data application to NOT use traefik in deployment.
