Fix typo in Makefile under photon
Fix version tag issue of redis container
Assign container name for redis container
Update docker compose template to enable network for redis
Remove exposed ports of redis from compose yaml tpl
This change involves using non-root user to run the process of the
docker images. Also made update in Dockerfile to make the containers
support "read-only" and introduce "HEALTHCHECK". Note the "read-only"
options are not enabled in docker-compose, to cover the very corner
case when user wants to update the container filesystem manually.
Remove read only option from docker-compose template by default
