Monitoring for Prod APIs

[maskaravivek]

As the APIs are now being consumed by Commons app on production, it would be great to have some sort of monitoring setup for the APIs.

A simple script that calls all the APIs every 30-60 minutes and checks if all the APIs are working as expected. We might be able to use Travis integration or use some open source status page for eg https://cachethq.io/ to have the monitoring setup.
