Linkerd - stable-2.13.4

stable-2.13.4

This stable release fixes a few issues in the proxy and in the outbound policy
API. Two new configuration options are also introduced to configure the
outbound (and inbound) cache discovery idle period for proxies. The
configuration is supported through annotations and through Helm values.

• Control Plane
• Fixed an issue where the namespace field on HTTPRoute backendRefs was
  ignored, and the backend Service would always be assumed to be in the
  namespace as the parent Service
• Fixed an issue where default authorizations generated for readiness and
  liveness probes would fail if the probe path included URI query parameters
• Added the ability to configure the proxy's discovery cache timeouts with
  the config.linkerd.io/proxy-outbound-discovery-cache-unused-timeout and
  config.linkerd.io/proxy-inbound-discovery-cache-unused-timeout annotations
• Fixed bug where topology routing would not disable while service was under
  load (thanks @MarkSRobinson!)
• Proxy
• Fixed an issue where meshed pods could not communicate with themselves
  through a ClusterIP Service
• Fixed an issue with W3C trace context propagation which caused proxy spans
  to be siblings rather than children of their original parent (thanks
  @whiskeysierra)
• Fixed the proxy not using gRPC response classification for gRPC requests to
  destinations without ServiceProfiles
• Helm
• Introduced outbound/inbound cache discovery cache idle timeout
  configuration values
