Very few resources need connection info, and rather than relying on
providers to set default for some resources, we are going to require
that connection blocks be explicitly set in the configuration.
In order for providers to determine if a computed value was unset in the
configuration, the configuration must be passed along with the prior and
proposed states. Terraform core will still handle the creation of the
ProposedNewState to ensure correctness, but the raw configuration value
will also be supplied for comparison.
The "config" package is no longer used and will be removed as part
of the 0.12 release cleanup. Since configschema is part of the
"new world" of configuration modelling, it makes more sense for
it to live as a subdirectory of the newer "configs" package.
The ImportResourceStateResponse command can return mutliple types.
ImportedResource maps the state to the appropriate type name, and also
allows providers to return Private data for each resource.
