gRPC bridge: fix unknowns in `Update` previews (#6006) 
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.

Pulumi Golang SDK

This directory contains support for writing Pulumi programs in the Go language. There are two aspects to this:

  • pulumi/ contains the client language bindings Pulumi program's code directly against;
  • pulumi-language-go/ contains the language host plugin that the Pulumi engine uses to orchestrate updates.

To author a Pulumi program in Go, simply say so in your Pulumi.yaml

name: <my-project>
runtime: go

and ensure you have pulumi-language-go on your path (it is distributed in the Pulumi download automatically).

By default, the language plugin will use your project's name, <my-project>, as the executable that it loads. This too must be on your path for the language provider to load it when you run pulumi preview or pulumi up.
