proxy: v2.217.0

[olix0r]

When connecting to a control plane API, the API server can return an HTTP response long before it returns the first stream response. To bound this time, we now enforce timeouts so that failures may result in attempting to use an alternate controller instances.

All controller response streams now use a generic gRPC middleware with initial, idle, and lifetime timeouts. When an initial timeout is encountered, a DeadlineExceeded grpc status is synthesized. When the other timeouts are encountered, the stream terminates gracefully.

These timeouts are configurable by the proxy injector. Timeouts are not enabled without configuration:

• LINKERD2_PROXY_CONTROL_STREAM_INITIAL_TIMEOUT
• LINKERD2_PROXY_CONTROL_STREAM_IDLE_TIMEOUT
• LINKERD2_PROXY_CONTROL_STREAM_LIFETIME

Each of these parameters is optional.
