Documentation suggestions:
It might be good to add a brief example here of an ACL, as we have the same
for the replication factor. Technically, the Access Control List is a list of
entries, each of the form `<u:USERNAME:[r-][w-][a-] | o::[r-][w-][a-]>[,...]`
`For example, to allow everyone read access and to allow alice read, write,
and admin access, the ACL would have two entries: "o::r,u:alice:rwa"`
Since there are multiple commands that take ACL option arguments, we might
want to just add some "ACL Example" to the end of the help text.
