These changes are a combination of three commits, each of which contributes to the testing and/or fixing of a problem with marshaling unknowns in `plugin.provider.Update` when `preview` is true. ## deploytest: add support for gRPC adapters. These changes add support for communicating with providers using the gRPC adapters to the deploytest pacakage. This makes it easier to test the gRPC adapters across typical lifecycle patterns. Supporting these changes are two additions to the `resource/plugin` package: 1. A type that bridges between the `plugin.Provider` interface and the `pulumirpc.ResourceProviderServer` 2. A function to create a `plugin.Provider` given a `pulumirpc.ResourceProviderClient` The deploytest package uses these to wrap an in-process `plugin.Provider` in a gRPC interface and connect to it without using the default plugin host, respectively. ## pulumi_test: test provider preview over gRPC. Add a test that runs the provider preview lifecycle, but using a provider that communicates over gRPC. ## gRPC bridge: fix unknowns in `Update` previews Set the `KeepUnknowns` and `RejectUnknowns` bits in the `MarshalOptions` used when unmarshaling update results to preserve unknowns during a preview and reject them otherwise. These changes also set the `RejectUnknowns` bit in the `MarshalOptions` used by `Create` if `preview` is false, and fix a bug in the array unmarshaler that could cause out-of-bounds accesses.
