Ability to restart a vertex of the pipeline

[Krithika3]

Summary

Today, if we want to restart a particular vertex (restart all the vertex pods) after changing some spec (like max payload size for jetstream), we need to restart every vertex pod individually. Here, we would like to have the ability to restart a particular vertex if that is doable

Use Cases

When would you use this? We would use this when we change specs like isbs spec, etc, or other config maps.
