Improve tracing support. (#3238) 
* Fix some tracing issues.

- Add endpoints for `startUpdate` and `postEngineEventsBatch` so that
  spans for these invocations have proper names
- Inject a tracing span when walking a plan so that resource operations
  are properly parented
- When handling gRPC calls, inject a tracing span into the call's
  metadata if no span is already present so that resource monitor and
  engine spans are properly parented
- Do not trace client gRPC invocations of the empty method so that these
  calls (which are used to determine server availability) do not muddy
  the trace. Note that I tried parenting these spans appropriately, but
  doing so broke the trace entirely.

With these changes, the only unparented span in a typical Pulumi
invocation is a single call to `getUser`. This span is unparented
because that call does not have a context available. Plumbing a context
into that particular call is surprisingly tricky, as it is often called
by other context-less functions.

* Make tracing support more flexible.

- Add support for writing trace data to a local file using Appdash
- Add support for viewing Appdash traces via the CLI

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.
