Implement header based http api rate limiter (server & client)

[fubhy]

What is the problem this feature would solve?

• Http servers enforcing & informing about current rate limiting status (via response headers)
• Http clients automatically respecting those rate limits

What is the feature you are proposing to solve the problem?

We should look into implementing a plug & play rate limiter server & client implementation for https://github.com/ietf-wg-httpapi/ratelimit-headers http header family.

The draft is currently expired (not sure what its latest status is) but various API services & solutions already implement different flavours of this, mostly varying in the used header names, including e.g. Envoy: https://www.envoyproxy.io/docs/envoy/latest/configuration/http/http_filters/router_filter#config-http-filters-router-x-envoy-ratelimited

What alternatives have you considered?
