Origin and Decisions

Extension is based on and heavily using vscode-go extension functionality and keeps it as submodule. Such decision to vendor extension was made in favor to simplify origin Gopium VSCode Extension development by reusing common components like: goutline codelens, tools installation, etc.

Nevertheless it's impossible to just seamlessly reuse another extension to build your own, so a lot of functionality has been patched and changed, most noticeable: vscode-go telemetry is disabled, vscode-go extension entrypoits are removed, go-outline is replaced with go-outline, etc.
