Make redis ttl configurable per environment

Currently the redis ttl is defaulted to 1 second. We want to make this configurable per environment due to high traffic in production environments. Since our current redis cache implementation is a short lived one, to mitigate the high usage in prd we want to be able to configure prd redis ttl to a higher number (20s). Please configure redis ttl using environment variable ENTV2_REDIS_TTL_SECONDS.
