Document login.links.xyz properties and defaults

Nowhere in cf-release is it mentioned that the 3 available login.links.xyz
properties are and what their default values are. This commit brings across
the current default values that login-server itself provides if
login.links.home or login.links.passwd or login.links.signup are not provided.

They are commented out so as to not force properties.login to be set
if the deployment file doesn't want it.
Explicitly set the 3 login.links properties

deploy collector as soon as possible

use case: when doing a deploy that moves collector between zones or
something, the old VM will be destroyed, which would mean without
deploying collector soon the rest of the deploy would be blind.
