Added route caching for 24 hours on all GET routes in countries.js. Added caching configurations in /config/apicache.js
that are determined by NODE_ENV. Added default NODE_ENV = 'local' to .env - this enables caching with all debug output.
If NODE_ENV is set to 'test', caching is disabled (this prevents unit tests from using the cache). Any other value of
NODE_ENV will result in the production config being used.
