Go dependency managment

Updating and adding new dependencies
------------------------------------

Add a Go dependency to your code, then:

    $ go mod tidy

All generated sources (eg. protobuf stubs) that are usually built by Bazel are invisible to go(mod)-based tooling. To get around this, we place `gomod-generated-placeholder.go` files in package directories that would otherwise contain generated files. These are ignored by Gazelle (and thus by Bazel builds) but not by go(mod)-based tooling.

Regenerating BUILDfiles
-----------------------

    $ bazel run //:gazelle
