Revert "Disable salt master and minions globally"

This reverts commit ec900482c3db820e1f24ba380040d466c35f705f.

The original reason for disabling salt globally was a slow
memory/process leak with the message queue in versions prior to
0.16. Ensuring salt packages are upgraded everywhere should mitigate
the issue.
