Security updates

[thunder-007]

DB passwords and private keys are exposed adding env vars will help hiding them While development create a .env file in cognizance_cms directory and set

DEBUG = TRUE
DB_NAME = ..
USER = ..
DB_PASSWORD = ..
HOST_USER = ..
HOST_PASSWORD = ..

They .. should be replaced with corresponding values without quotes using os.environ["KEY_NAME"] will return corresponding value as string
In production you can find config vars under setting in heroku add the key and value as show below using debug as environment variable helps you in quick debug in production you can simply change the value again after finding the cause error : )
