-`ethereum-package-client` describes which client is running on the node.
-`ethereum-package-client-image` describes the image that is used for the client.
-`ethereum-package-client-type` describes the type of client that is running on the node (`execution`,`beacon` or `validator`).
-`ethereum-package-connected-client` describes the CL/EL client that is connected to the EL/CL client.
