🚀 Features
GraphOS Enterprise: Coprocessor read access to request uri, method and HTTP response status codes (Issue #2861, Issue #2861)
We've added the ability for coprocessors to have read-only access to additional contextual information at the RouterService and SubgraphService stages:
The RouterService stage now has read-only access to these client request properties:
path(e.g.,/graphql)method(e.g.,POST,GET)
The RouterService stage now has read-only access to these client response properties:
status_code(e.g.403,200)
The SubgraphService stage now has read-only access to these subgraph response properties:
status_code(e.g.,503,200)

🐛 Fixes
Coprocessors: Empty body requests from GET requests are now deserialized without error
Fixes a bug where a coprocessor operating at the router_request stage would fail to deserialize an empty body, which is typical for GET requests.

📃 Configuration
Helm: Router chart now supports extraLabels for Deployments/Pods
Our Helm chart now supports a new value called extraLabels, which enables chart users to add custom labels to the Router Deployment and its Pods.

Helm: Router chart now supports extraContainers to run sidecars
Our Helm chart now supports extraContainers in an effort to simplify the ability to run containers alongside Router containers (sidecars) which is a useful pattern for coprocessors.
Migrate away from unimplemented coprocessor.subgraph.all.response.uri
We have removed a completely unimplemented coprocessor.subgraph.all.response.uri key from our configuration. It had no effect, but we will automatically migrate configurations which did use it, resulting in no breaking changes by this removal.

Example: Rhai-based cache-control response header management
A new Rhai example demonstrates how to recreate some of the behavior of Apollo Gateway's subgraph cache-control response header behavior. This addresses some of the need identified in #326.
