Sometime back, I too went through this, but got adjusted to the thought
that the template validation is really for validating the syntax and
structure of a template. Whether the values provided are valid or not
will be decided when the stack is validated. The values that depend on
resource plugins to fetch data from other services are not validated,
and to me it makes sense. It helps user to quickly test-develop
templates that are syntactically and structurally valid and they don't
have to depend on resource plugins and services availability. IMO, it
would be better to document the way template validate works, than to
make it a heavy weight request that depends on plugins and services.
