    Eager-load properties for nested resource list

    When doing "openstack stack resource list --nested-depth=n", we were
    lazy-loading the resources' properties data. This is expensive, especially
    when there are a large number of resources. Eager-load the data, as we
    always use it to show the resources.

    For consistency, always eager-load the resource 'data' (even in
    resource_get), because the Resource versioned object accesses it
    unconditionally.
