Document clear behaviour of list options

More general for all list options.

Seems to currently affect:
lxc.network (clear all NICs)
lxc.network.* (clear current NIC)
lxc.cap.drop
lxc.cap.keep
lxc.cgroup
lxc.mount.entry
lxc.mount.auto
lxc.hook
lxc.id_map
lxc.group
lxc.environment

       Each option in the configuration file has the form <command>key
       = value</command> fitting in one line. The '#' character means
-      the line is a comment.
+      the line is a comment. List options, like capabilities and cgroups
+      options, can be used with no value to clear any previously
+      defined values of that option.
