Ralph Castain 9b8473fdbf Cleanup orted cmd line - we don't need to pass nodenames, and shouldn't pass heartbeat unless the orted is going to use it. This helps shorten the cmd line for future use.
Cleanup when an orted actually opens the PLM. Unfortunately, some unmentionable people are pushing head node environs out to remote nodes, causing the daemons to think they are the HNP. This helps prevent the confusion.

This commit was SVN r19518.
