Aaron Lehmann 41b84e0994 cli: Change autolock flag description
This change incorporates feedback from @thaJeztah in the PR that added
the autolock flag. It changes the descriptions to be different for
"swarm init" and "swarm update" so that the boolean nature so that the
purpose of the flag in both contexts is clearer.
