    golang: Go modules support; Prepare to deprecate GOPATH · 73ff1a8d

    Add support for using Go modules to golang/gowork infrastructure:
    
    - Users can now request to install a module via gowork:install as. e.g.
      in the following example:
    
    	[gowork]
    	install =
    	    lab.nexedi.com/kirr/neo/go/...@v0.0.0-20210103165133-f3effa6c535f
    	    golang.org/x/tools/gopls@v0.4.3
    	    ${helloweb:location}/go:./...
    
      The first two request to install programs from an external module at particular
      revision/version. The latter requests to install programs from locally
      cloned/checked-out module source.
    
      The documentation now talks only about programs, because "package
      installation" became unnecessary long time ago as Go toolchain uses
      right packages and recompiles things as needed automatically since
      introduction of the Go build cache in go 1.10.
    
    - The change comes accompanied by corresponding helloweb change that
      reworks it to a) become a module itself, and b) to use other modules -
      that are not explicitly cloned by buildout - so that we can be sure
      that module way of fetching/building things actually works.

    - Non-module way - e.g. build via GOPATH - is still supported (because
      e.g. software/gitlab still uses it), but not explicitly documented and
      scheduled to be deprecated and removed. The reason for this is that
      upstream Go is going to remove support for GOPATH and leave only
      module-based approach in Go1.17
