Update dns.rst

Updated command syntax for dynamic dns - changed set service dns dynamic interface to set service dns dynamic address. 

Changed the login option from 'login' to 'username' 

Changed the web options from 'use-web' to 'web-options' 

Changed because I ran into the command syntax change on a 1.4 install. Updating documents to match.
