>From a K8s integration perspective it's preferable that some sidecar framework component could update the task's DiscoveryInfo vs. putting all of that responsibility on the executor.

> K8s tasks can dynamically update what they expose to make discoverable by the cluster. Unfortunately, all DiscoveryInfo the cluster is immutable, at the time of task start. 
> We would like to enable DiscoveryInfo to be dynamically updatable, so that executors can change what they're advertising based on their internal state, versus requiring DiscoveryInfo to be known prior to starting the tasks.
