Use Kubernetes Cli Python Watches

[Paige Patton]

We're trying to rework our current code base to allow for more scalability and security. There are a couple of instances where we could use watches instead of polling every few seconds, this will help with not overwhelming the etcd on the cluster. Watches provide a more efficient detection, as explained in Kubernetes API Concepts.

This work will need to be used on both the wait_for_ready_status and wait_for_ready_status functions in common_node_functions.py

Will also want to assess other places that we could use watching instead of polling ourselves
