Circuit breaking at Weaver

[rShetty]

• Introduce and implement circuit breaker pattern for weaver

[kartik7153]

Why do we need a circuit breaker here? It's a proxy right. What fallbacks you will be implementing for this?

[rShetty]

@rShetty This has not been well thought yet, but we would need a way to actively check for failures from downstreams and fallback to a user configured standard fallbacks. Needs analysis, more on how it is done in Envoy here: https://www.envoyproxy.io/learn/circuit-breaking
