## Feature implementation

Release managers will continue to have a final say in what gets merged or not, unless directed by the TOC. See the next
section if the implementation is done, but a bug is being addressed.

  // not specified, the specified Kind must be in the core API group. For any

  // name is the name of resource being referenced.
  optional string name = 3;

Goals:
- Improve upgrade experience: users should be able to gradually roll upgrades, with proper
canary deployments for Istio components. It should be possible to deploy a new version while keeping the
stable version in place and gradually migrate apps to the new version.

- More flexibility: the new installer allows multiple 'environments', allowing applications to select

// This is a subresource of Pod.  A request to cause such an eviction is
// created by POSTing to .../pods/<pod name>/evictions.
message Eviction {
  // ObjectMeta describes the pod that is being evicted.
