Autocompletion for Go layer is broken for imported packages with latest version

[p554157atch]

With latest version of Golang Gomodules becomes the default thing! sigh.
And GOCODE and many other outdated tools won't support this stuff.

The company-go package wast last updated 4 years ago:
https://github.com/emacsmirror/company-go/blob/master/company-go.el

It does not support:
https://github.com/golang/tools/blob/master/gopls/doc/user.md

Spacemacs should move to gopls or something better and remove support for old code that calls gocode that no longer works with any kind of imports.

See this issue:
nsf/gocode#537

GOCODE IS not maintained anymore:
https://develop.spacemacs.org/layers/+lang/go/README.html

Move to GOPLS or something better,
Remove GOCODE from documentation.

@p554157atch there is no moving to gopls as spacemacs already has full LSP support aka also support for latest gopls. The reason why LSP is not the default for most layers is that it requires a separate setup step which not all users are willing to go through.

If the alternative backend is not longer maintained we will shift the default to LSP like we did with the scala layer.
If you want to speed things up please have a look at the other tools loaded in that layer and point out which of these are obsolete nowadays and I can adapt it.

Remember this is a communities project, there is no way we (maintainers) can keep track of outdated packages in the individual layers, this must be fixed or at least reported by people using this language.

I have started changing the layer to be favouring gopls over go-mode by default. However I am unsure how much of the given tools are actually needed when LSP is activated.

Can someone more familiar with go have a look and post a list of packages which are not longer working in this layer?
Till I have some more information I will remove company-go but keep the rest of the packages.

I am through, the layer documentation now clearly explains which backends are available and deprecates go-mode. The layer uses the standard way to select a backend, this is if lsp-layer is loaded gopls is used if not found go-mode is used otherwise.

I am closing this ticket for now. If more packages are found which must be replaced in that layer this issue should be reopened.

Thank you!
