Code review comment for ~bjornt/maas:peer-proxy-ui

I really like splitting NTP and DNS into different sections, it makes the page much easier to read. I think we may want to use a drop down to select the proxy mode. The text field would be disabled for don't use and built-in. I'd ask Maria from design this before reworking incase I'm wrong.

I poked around and can't figure out why MAAS.templates is currently broken and wasn't able to come up with anything, Blake might know.
