Add new field to libpod to indicate whether or not to use labelling

Also update some missing fields libpod.conf obtions in man pages.

Fix sort order of security options and add a note about disabling
labeling.

When a process requests a new label.  libpod needs to reserve all
labels to make sure that their are no conflicts.
