Need to revisit how we handle ctrl_alt_del

[michael-riddle]

Currently to disable ctrl_alt_del we jam in a ctrl-alt-del.target and a ctrl-alt-del-capture.service file and then handle their restarts with exec. Based on the latest versions of cis, dis, and ssg, we could probably control this with an actual puppet service resource and still meet the requirements of the standards without having messy execs and hard-coded files.
