Remote Execution (REX) is a crucial plugin for many users. When reading the Managing Hosts (6.18) guide it is used all over the place. In particular, https://docs.redhat.com/en/documentation/red_hat_satellite/6.18/html/managing_hosts/configuring_and_setting_up_remote_jobs_managing-hosts describes the different modes how it can be set up.

Acceptance criteria:
