Avoid sticky environment config

[meissadia]

To improve application configurability, without the need for full application redeployment, we use a Github hosted JSON configuration file.

When we update this configuration, we've experience instances where it takes 5+ minutes for the new configuration to be reflected in our Production app.

I would like to explore adjusting the cache headers when fetching this config in an attempt to avoid the "sticky config" and by bypassing the caching of this file.
