These changes address the following warning showing up on `go get`
operations:
go: module github.com/golang/protobuf is deprecated: Use the
"google.golang.org/protobuf" module instead.
All changes are made using the recommendations in the per-function
deprecation notices from the docs at
https://pkg.go.dev/github.com/golang/protobuf/ptypes
Built-in Plugins
This directory contains all the "built-in" plugins. These are real plugins, they dogfood the full plugin SDK, do not depend on any internal packages, and they are executed via subprocess just like a real plugin would be.
The difference is that these plugins are linked directly into the single command binary. We do this currently for ease of development of the project. In future we will split these out into standalone repositories and binaries.
