If a resource's options bag does not specify `protect` or `provider`, pull a default value from the resource's parent. In order to allow a parent resource to specify providers for multiple resource types, component resources now accept an optional map from package name to provider instance. When a custom resource needs a default provider from its parent, it checks its parent provider bag for an entry under its package. If a component resource does not have a provider bag, its pulls a default from its parent. These changes also add a `parent` field to `InvokeOptions` s.t. calls to invoke can use the same behavior as resource creation w.r.t. providers. Fixes #1735, #1736.
