[JENKINS-62925] terminology update: remove the usage of the master and slave terms

The support core plugin is still using the terminology slave for the files / directory / error message it produces. For example the agent's directory are collected under nodes/slave/, agent's remoting version is shown as "Slave Version", ...

Those should be replaced accordingly with the term agent

Addiitonally 'master' must be renamed to 'controller' as per https://issue-redirect.jenkins.io/issue/65398

• environment: support-core:2.69

Start in the support-core-plugin code by searching for the reported nodes/slave/ directory name, "Slave Version", and other master/slave terminology. Replace the affected terminology with agent/controller where appropriate, then verify that the produced files, directories, and error messages use the requested names.
