Use Control Plane instead of Master (#18438)

Browse Source 
* Use Control Plane instead of Master

* improve image. The SVG was not matching the PNG, so I basically had to re-create it from scratch. I kept the visual similarities as mush as possible

* remove tautological phrase

* fix glossary references as well

* improve cluster glossary to move from Master to Control Plane

* improve english form

The worker node(s) host the pods that are the components of the application. The master node(s) manages the worker nodes and the pods in the cluster. Multiple master nodes are used to provide a cluster with failover and high availability.
The worker node(s) host the pods that are the components of the application. The Control Plane manages the worker nodes and the pods in the cluster. In production environments, the Control Plane usually runs across multiple computers and a cluster usually runs multiple nodes, providing fault-tolerance and high availability.
