Fix flag description for --host-add

Browse Source 
The `--host-add` flag adds a new `host:ip` mapping. Even though
adding an entry is idempotent (adding the same mapping multiple
times does not update the service's definition), it does not
_update_  an existing mapping with a new IP-address (multiple
IP-addresses can be defined for a host).

This patch removes the "or update" part from the flag's
description.
