It is a follow-up to JENKINS-58483 . Jenkins core currently includes Jenkins CLI as a dependency, and hence there is no way to split the CLI code and the Core codebase. There is little justification to keep the dependency, and IMHO we should not do so.

With this change, jenkins.py will have just another regression due to the removal of the deprecated connection INFO class. But I doubt this code is alive after JEP-200 anyway
