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
You want to know something silly? There are multiple versions of
go-bindata floating around in the world, and they have different
features and flags.
This httpfs package was written with
https://github.com/go-bindata/go-bindata and uses the -fs flag. Most
everyone else (nixpkgs, homebrew) seems to have moved over to this fork
https://github.com/kevinburke/go-bindata, which does not have that
feature.
Run `go generate` with this installed and you'll get an error like `flag
provided but not defined: -fs`.
It looks like `httpfs` is the odd one out here, and it's not used
anywhere I can find either here or waypoint, so let's just remove it so
we can `go generate` cleanly with the version of go-bindata that most
people are using.
