This improves the failure messages in two circumstances: 1) If the resource monitor RPC connection is missing. This can happen two ways: either you run a Pulumi program using vanilla Node.js, instead of the CLI, or you've accidentally loaded the Pulumi SDK more than once. 2) Failure to load the custom Pulumi SDK Node.js extension. This is a new addition and would happen if you tried running a Pulumi program using a vanilla Node.js, rather than using the Pulumi CLI.
