Caching of common Bhashini APIs

[ChakshuGautam]

1. Every request that has already been served by Bhashini (STT, TTS) should be cached.
2. Status message should be divided into two parts => "new" + "static" (which should come from cached APIs)

Create a transparent proxy in fronte of Bhashini to store and give responses to these APIs. Since the number of requests could be huge, this should a CDN-driven transparent proxy.

This would be an application agnostic proxy so can be deployed to any application to speed up queries without changing application code.
