'Retrieve the value for this view according to the template.
The `template` against which the values are checked can be
anything convertible to a `Template` using `as_template`. This
means you can pass in a default integer or string value, for
example, or a type to just check that something matches the type
you expect.
May raise a `ConfigValueError` (or its subclass,
`ConfigTypeError`) or a `NotFoundError` when the configuration
doesn\'t satisfy the template.'
