Pull Request (PR) description

Breaking change for existing instances.
This PR is designed to refactor the "master" and "slave" terminology used by the puppet-jenkins module to be more inclusive, more appropriate and as per the newer stance on this terminology by Jenkins. Replacing these terms with the Jenkins preferred "controller" and "agent" terminology as noted by Marky Jackson in 2020 - https://www.jenkins.io/blog/2020/06/18/terminology-update/

This is a fantastic module and it is a real shame it still uses this terminology (master / slave), whilst valid for describing the technical relationship between the components and has historically been used across a wide array of software and technology, it doesn't provide a great outcome for the people side of IT and development, and some individuals may be offended or feel strongly against this as it isn't a favorable term based on it's history. As a member of a progressive university, I believe it is my social responsibility to enact change where I am able to, a few of my colleagues also raised similar issues with the naming convention hence why I've spent the time to refactor the code.

The change is a significant change to the module from a naming perspective, however it should be possible to refactor the references in one's code base to then move / recreate the appropriate directory to use this new version. All internal Jenkins calls to ie sshslaves have been left in tact as changes cannot be made to these elements without breaking the module.
